Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19468, here are decompositions:

  • 5 + 19463 = 19468
  • 11 + 19457 = 19468
  • 41 + 19427 = 19468
  • 47 + 19421 = 19468
  • 89 + 19379 = 19468
  • 149 + 19319 = 19468
  • 167 + 19301 = 19468
  • 179 + 19289 = 19468

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19468 first appears in π at position 146,138 of the decimal expansion (the 146,138ordinal-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.
