Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488666, here are decompositions:

  • 127 + 488539 = 488666
  • 163 + 488503 = 488666
  • 193 + 488473 = 488666
  • 313 + 488353 = 488666
  • 337 + 488329 = 488666
  • 349 + 488317 = 488666
  • 379 + 488287 = 488666
  • 433 + 488233 = 488666

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 488,666 and was likely granted around 1892.

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

Position in π

The digit sequence 488666 first appears in π at position 955,181 of the decimal expansion (the 955,181ordinal-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.
