Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19654, here are decompositions:

  • 71 + 19583 = 19654
  • 83 + 19571 = 19654
  • 101 + 19553 = 19654
  • 113 + 19541 = 19654
  • 191 + 19463 = 19654
  • 197 + 19457 = 19654
  • 227 + 19427 = 19654
  • 233 + 19421 = 19654

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19654 first appears in π at position 211,837 of the decimal expansion (the 211,837ordinal-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.
