Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75742, here are decompositions:

  • 11 + 75731 = 75742
  • 53 + 75689 = 75742
  • 59 + 75683 = 75742
  • 83 + 75659 = 75742
  • 89 + 75653 = 75742
  • 101 + 75641 = 75742
  • 113 + 75629 = 75742
  • 131 + 75611 = 75742

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 75742 first appears in π at position 25,325 of the decimal expansion (the 25,325ordinal-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.
