Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723542, here are decompositions:

  • 11 + 8723531 = 8723542
  • 59 + 8723483 = 8723542
  • 83 + 8723459 = 8723542
  • 101 + 8723441 = 8723542
  • 239 + 8723303 = 8723542
  • 419 + 8723123 = 8723542
  • 461 + 8723081 = 8723542
  • 479 + 8723063 = 8723542

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 8,723,542 and was likely granted around 2014.

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

Position in π

The digit sequence 8723542 first appears in π at position 838,588 of the decimal expansion (the 838,588ordinal-suffix:th 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.
