Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515044, here are decompositions:

  • 3 + 515041 = 515044
  • 191 + 514853 = 515044
  • 197 + 514847 = 515044
  • 251 + 514793 = 515044
  • 293 + 514751 = 515044
  • 311 + 514733 = 515044
  • 401 + 514643 = 515044
  • 521 + 514523 = 515044

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 515,044 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 515044 first appears in π at position 489,676 of the decimal expansion (the 489,676ordinal-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.
