Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530900, here are decompositions:

  • 3 + 530897 = 530900
  • 31 + 530869 = 530900
  • 43 + 530857 = 530900
  • 67 + 530833 = 530900
  • 103 + 530797 = 530900
  • 127 + 530773 = 530900
  • 157 + 530743 = 530900
  • 199 + 530701 = 530900

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 530,900 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 530900 first appears in π at position 242,090 of the decimal expansion (the 242,090ordinal-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.
