Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487902, here are decompositions:

  • 5 + 487897 = 487902
  • 11 + 487891 = 487902
  • 13 + 487889 = 487902
  • 29 + 487873 = 487902
  • 59 + 487843 = 487902
  • 71 + 487831 = 487902
  • 73 + 487829 = 487902
  • 83 + 487819 = 487902

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 487,902 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 487902 first appears in π at position 445,105 of the decimal expansion (the 445,105ordinal-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.
