Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545230, here are decompositions:

  • 17 + 545213 = 545230
  • 41 + 545189 = 545230
  • 89 + 545141 = 545230
  • 113 + 545117 = 545230
  • 137 + 545093 = 545230
  • 167 + 545063 = 545230
  • 173 + 545057 = 545230
  • 197 + 545033 = 545230

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 545,230 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 545230 first appears in π at position 241,267 of the decimal expansion (the 241,267ordinal-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.
