Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520578, here are decompositions:

  • 7 + 520571 = 520578
  • 11 + 520567 = 520578
  • 29 + 520549 = 520578
  • 31 + 520547 = 520578
  • 127 + 520451 = 520578
  • 131 + 520447 = 520578
  • 151 + 520427 = 520578
  • 167 + 520411 = 520578

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 520,578 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 520578 first appears in π at position 404,511 of the decimal expansion (the 404,511ordinal-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.
