Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545028, here are decompositions:

  • 5 + 545023 = 545028
  • 67 + 544961 = 545028
  • 101 + 544927 = 545028
  • 109 + 544919 = 545028
  • 131 + 544897 = 545028
  • 139 + 544889 = 545028
  • 149 + 544879 = 545028
  • 151 + 544877 = 545028

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 545,028 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 545028 first appears in π at position 501,872 of the decimal expansion (the 501,872ordinal-suffix:nd 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.
