Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524820, here are decompositions:

  • 17 + 524803 = 524820
  • 19 + 524801 = 524820
  • 31 + 524789 = 524820
  • 89 + 524731 = 524820
  • 113 + 524707 = 524820
  • 137 + 524683 = 524820
  • 139 + 524681 = 524820
  • 151 + 524669 = 524820

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 524,820 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 524820 first appears in π at position 453,029 of the decimal expansion (the 453,029ordinal-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.
