Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37830, here are decompositions:

  • 17 + 37813 = 37830
  • 19 + 37811 = 37830
  • 31 + 37799 = 37830
  • 47 + 37783 = 37830
  • 83 + 37747 = 37830
  • 113 + 37717 = 37830
  • 131 + 37699 = 37830
  • 137 + 37693 = 37830

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 37830 first appears in π at position 106,678 of the decimal expansion (the 106,678ordinal-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.
