Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10900, here are decompositions:

  • 11 + 10889 = 10900
  • 17 + 10883 = 10900
  • 41 + 10859 = 10900
  • 47 + 10853 = 10900
  • 53 + 10847 = 10900
  • 101 + 10799 = 10900
  • 167 + 10733 = 10900
  • 191 + 10709 = 10900

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10900 first appears in π at position 22,303 of the decimal expansion (the 22,303ordinal-suffix:rd 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.
