Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75800, here are decompositions:

  • 3 + 75797 = 75800
  • 7 + 75793 = 75800
  • 13 + 75787 = 75800
  • 19 + 75781 = 75800
  • 79 + 75721 = 75800
  • 97 + 75703 = 75800
  • 181 + 75619 = 75800
  • 223 + 75577 = 75800

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 75800 first appears in π at position 21,152 of the decimal expansion (the 21,152ordinal-suffix:nd 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.
