Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515254, here are decompositions:

  • 17 + 515237 = 515254
  • 23 + 515231 = 515254
  • 101 + 515153 = 515254
  • 167 + 515087 = 515254
  • 401 + 514853 = 515254
  • 431 + 514823 = 515254
  • 461 + 514793 = 515254
  • 503 + 514751 = 515254

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 515,254 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 515254 first appears in π at position 265,665 of the decimal expansion (the 265,665ordinal-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.
