Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487580, here are decompositions:

  • 19 + 487561 = 487580
  • 73 + 487507 = 487580
  • 103 + 487477 = 487580
  • 109 + 487471 = 487580
  • 151 + 487429 = 487580
  • 157 + 487423 = 487580
  • 193 + 487387 = 487580
  • 199 + 487381 = 487580

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 487,580 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 487580 first appears in π at position 846,993 of the decimal expansion (the 846,993ordinal-suffix:rd 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.
