Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515546, here are decompositions:

  • 7 + 515539 = 515546
  • 223 + 515323 = 515546
  • 313 + 515233 = 515546
  • 373 + 515173 = 515546
  • 397 + 515149 = 515546
  • 457 + 515089 = 515546
  • 607 + 514939 = 515546
  • 613 + 514933 = 515546

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 515,546 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 515546 first appears in π at position 566,439 of the decimal expansion (the 566,439ordinal-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.
