Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520542, here are decompositions:

  • 13 + 520529 = 520542
  • 109 + 520433 = 520542
  • 131 + 520411 = 520542
  • 149 + 520393 = 520542
  • 163 + 520379 = 520542
  • 173 + 520369 = 520542
  • 179 + 520363 = 520542
  • 181 + 520361 = 520542

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 520,542 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 520542 first appears in π at position 300,005 of the decimal expansion (the 300,005ordinal-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.
