Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545162, here are decompositions:

  • 19 + 545143 = 545162
  • 31 + 545131 = 545162
  • 73 + 545089 = 545162
  • 139 + 545023 = 545162
  • 199 + 544963 = 545162
  • 283 + 544879 = 545162
  • 349 + 544813 = 545162
  • 439 + 544723 = 545162

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 545,162 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 545162 first appears in π at position 80,519 of the decimal expansion (the 80,519ordinal-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.
