Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523930, here are decompositions:

  • 3 + 523927 = 523930
  • 23 + 523907 = 523930
  • 53 + 523877 = 523930
  • 83 + 523847 = 523930
  • 101 + 523829 = 523930
  • 137 + 523793 = 523930
  • 167 + 523763 = 523930
  • 257 + 523673 = 523930

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 523,930 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 523930 first appears in π at position 898,029 of the decimal expansion (the 898,029ordinal-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.
