Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520628, here are decompositions:

  • 7 + 520621 = 520628
  • 19 + 520609 = 520628
  • 61 + 520567 = 520628
  • 79 + 520549 = 520628
  • 181 + 520447 = 520628
  • 271 + 520357 = 520628
  • 331 + 520297 = 520628
  • 337 + 520291 = 520628

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 520,628 and was likely granted around 1894.

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

Position in π

The digit sequence 520628 first appears in π at position 129,531 of the decimal expansion (the 129,531ordinal-suffix:st 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.
