Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520784, here are decompositions:

  • 37 + 520747 = 520784
  • 67 + 520717 = 520784
  • 151 + 520633 = 520784
  • 163 + 520621 = 520784
  • 337 + 520447 = 520784
  • 373 + 520411 = 520784
  • 421 + 520363 = 520784
  • 487 + 520297 = 520784

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 520,784 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 520784 first appears in π at position 859,185 of the decimal expansion (the 859,185ordinal-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.
