Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18976, here are decompositions:

  • 3 + 18973 = 18976
  • 17 + 18959 = 18976
  • 29 + 18947 = 18976
  • 59 + 18917 = 18976
  • 107 + 18869 = 18976
  • 137 + 18839 = 18976
  • 173 + 18803 = 18976
  • 179 + 18797 = 18976

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18976 first appears in π at position 33,417 of the decimal expansion (the 33,417ordinal-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.
