Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19546, here are decompositions:

  • 3 + 19543 = 19546
  • 5 + 19541 = 19546
  • 83 + 19463 = 19546
  • 89 + 19457 = 19546
  • 113 + 19433 = 19546
  • 167 + 19379 = 19546
  • 173 + 19373 = 19546
  • 227 + 19319 = 19546

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19546 first appears in π at position 193,003 of the decimal expansion (the 193,003ordinal-suffix:rd 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.
