Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19102, here are decompositions:

  • 23 + 19079 = 19102
  • 29 + 19073 = 19102
  • 71 + 19031 = 19102
  • 89 + 19013 = 19102
  • 101 + 19001 = 19102
  • 191 + 18911 = 19102
  • 233 + 18869 = 19102
  • 263 + 18839 = 19102

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19102 first appears in π at position 51,946 of the decimal expansion (the 51,946ordinal-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.
