Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19492, here are decompositions:

  • 3 + 19489 = 19492
  • 23 + 19469 = 19492
  • 29 + 19463 = 19492
  • 59 + 19433 = 19492
  • 71 + 19421 = 19492
  • 89 + 19403 = 19492
  • 101 + 19391 = 19492
  • 113 + 19379 = 19492

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19492 first appears in π at position 37,144 of the decimal expansion (the 37,144ordinal-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.
