Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39830, here are decompositions:

  • 3 + 39827 = 39830
  • 31 + 39799 = 39830
  • 61 + 39769 = 39830
  • 97 + 39733 = 39830
  • 103 + 39727 = 39830
  • 127 + 39703 = 39830
  • 151 + 39679 = 39830
  • 163 + 39667 = 39830

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39830 first appears in π at position 205,159 of the decimal expansion (the 205,159ordinal-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.
