Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23842, here are decompositions:

  • 11 + 23831 = 23842
  • 23 + 23819 = 23842
  • 29 + 23813 = 23842
  • 41 + 23801 = 23842
  • 53 + 23789 = 23842
  • 89 + 23753 = 23842
  • 101 + 23741 = 23842
  • 173 + 23669 = 23842

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23842 first appears in π at position 55,750 of the decimal expansion (the 55,750ordinal-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.
