Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487520, here are decompositions:

  • 13 + 487507 = 487520
  • 31 + 487489 = 487520
  • 43 + 487477 = 487520
  • 73 + 487447 = 487520
  • 97 + 487423 = 487520
  • 139 + 487381 = 487520
  • 157 + 487363 = 487520
  • 307 + 487213 = 487520

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 487,520 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 487520 first appears in π at position 734,076 of the decimal expansion (the 734,076ordinal-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.
