Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515002, here are decompositions:

  • 53 + 514949 = 515002
  • 113 + 514889 = 515002
  • 149 + 514853 = 515002
  • 179 + 514823 = 515002
  • 233 + 514769 = 515002
  • 251 + 514751 = 515002
  • 263 + 514739 = 515002
  • 269 + 514733 = 515002

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 515,002 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 515002 first appears in π at position 120,208 of the decimal expansion (the 120,208ordinal-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.
