Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545506, here are decompositions:

  • 23 + 545483 = 545506
  • 29 + 545477 = 545506
  • 239 + 545267 = 545506
  • 293 + 545213 = 545506
  • 317 + 545189 = 545506
  • 389 + 545117 = 545506
  • 419 + 545087 = 545506
  • 443 + 545063 = 545506

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 545,506 and was likely granted around 1895.

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

Position in π

The digit sequence 545506 first appears in π at position 151,990 of the decimal expansion (the 151,990ordinal-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.
