Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530638, here are decompositions:

  • 29 + 530609 = 530638
  • 41 + 530597 = 530638
  • 71 + 530567 = 530638
  • 89 + 530549 = 530638
  • 107 + 530531 = 530638
  • 131 + 530507 = 530638
  • 137 + 530501 = 530638
  • 191 + 530447 = 530638

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 530,638 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 530638 first appears in π at position 330,484 of the decimal expansion (the 330,484ordinal-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.
