Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17972, here are decompositions:

  • 13 + 17959 = 17972
  • 43 + 17929 = 17972
  • 61 + 17911 = 17972
  • 109 + 17863 = 17972
  • 181 + 17791 = 17972
  • 211 + 17761 = 17972
  • 223 + 17749 = 17972
  • 313 + 17659 = 17972

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17972 first appears in π at position 392,011 of the decimal expansion (the 392,011ordinal-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.
