Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91830, here are decompositions:

  • 7 + 91823 = 91830
  • 17 + 91813 = 91830
  • 19 + 91811 = 91830
  • 23 + 91807 = 91830
  • 29 + 91801 = 91830
  • 59 + 91771 = 91830
  • 73 + 91757 = 91830
  • 97 + 91733 = 91830

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 91830 first appears in π at position 65,777 of the decimal expansion (the 65,777ordinal-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.
