Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618828, here are decompositions:

  • 19 + 8618809 = 8618828
  • 79 + 8618749 = 8618828
  • 139 + 8618689 = 8618828
  • 271 + 8618557 = 8618828
  • 349 + 8618479 = 8618828
  • 499 + 8618329 = 8618828
  • 541 + 8618287 = 8618828
  • 571 + 8618257 = 8618828

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,618,828 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8618828 first appears in π at position 905,041 of the decimal expansion (the 905,041ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
