Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19950, here are decompositions:

  • 13 + 19937 = 19950
  • 23 + 19927 = 19950
  • 31 + 19919 = 19950
  • 37 + 19913 = 19950
  • 59 + 19891 = 19950
  • 61 + 19889 = 19950
  • 83 + 19867 = 19950
  • 89 + 19861 = 19950

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19950 first appears in π at position 13,864 of the decimal expansion (the 13,864ordinal-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.
