Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487120, here are decompositions:

  • 41 + 487079 = 487120
  • 47 + 487073 = 487120
  • 71 + 487049 = 487120
  • 107 + 487013 = 487120
  • 113 + 487007 = 487120
  • 149 + 486971 = 487120
  • 173 + 486947 = 487120
  • 191 + 486929 = 487120

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 487,120 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 487120 first appears in π at position 261,278 of the decimal expansion (the 261,278ordinal-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.
