Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26040, here are decompositions:

  • 11 + 26029 = 26040
  • 19 + 26021 = 26040
  • 23 + 26017 = 26040
  • 37 + 26003 = 26040
  • 41 + 25999 = 26040
  • 43 + 25997 = 26040
  • 59 + 25981 = 26040
  • 71 + 25969 = 26040

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26040 first appears in π at position 33,541 of the decimal expansion (the 33,541ordinal-suffix:st 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.
