Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487172, here are decompositions:

  • 61 + 487111 = 487172
  • 73 + 487099 = 487172
  • 79 + 487093 = 487172
  • 151 + 487021 = 487172
  • 181 + 486991 = 487172
  • 223 + 486949 = 487172
  • 229 + 486943 = 487172
  • 571 + 486601 = 487172

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 487,172 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 487172 first appears in π at position 617,131 of the decimal expansion (the 617,131ordinal-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.
