Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545212, here are decompositions:

  • 23 + 545189 = 545212
  • 71 + 545141 = 545212
  • 149 + 545063 = 545212
  • 179 + 545033 = 545212
  • 233 + 544979 = 545212
  • 251 + 544961 = 545212
  • 293 + 544919 = 545212
  • 419 + 544793 = 545212

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 545,212 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 545212 first appears in π at position 300,574 of the decimal expansion (the 300,574ordinal-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.
