Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19882, here are decompositions:

  • 29 + 19853 = 19882
  • 41 + 19841 = 19882
  • 89 + 19793 = 19882
  • 131 + 19751 = 19882
  • 173 + 19709 = 19882
  • 311 + 19571 = 19882
  • 419 + 19463 = 19882
  • 449 + 19433 = 19882

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19882 first appears in π at position 113,696 of the decimal expansion (the 113,696ordinal-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.
