Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19836, here are decompositions:

  • 17 + 19819 = 19836
  • 23 + 19813 = 19836
  • 43 + 19793 = 19836
  • 59 + 19777 = 19836
  • 73 + 19763 = 19836
  • 83 + 19753 = 19836
  • 97 + 19739 = 19836
  • 109 + 19727 = 19836

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19836 first appears in π at position 262,604 of the decimal expansion (the 262,604ordinal-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.
