Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502728, here are decompositions:

  • 11 + 502717 = 502728
  • 29 + 502699 = 502728
  • 41 + 502687 = 502728
  • 59 + 502669 = 502728
  • 97 + 502631 = 502728
  • 131 + 502597 = 502728
  • 137 + 502591 = 502728
  • 179 + 502549 = 502728

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 502,728 and was likely granted around 1893.

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

Position in π

The digit sequence 502728 first appears in π at position 307,743 of the decimal expansion (the 307,743ordinal-suffix:rd 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.
