Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33180, here are decompositions:

  • 19 + 33161 = 33180
  • 29 + 33151 = 33180
  • 31 + 33149 = 33180
  • 61 + 33119 = 33180
  • 67 + 33113 = 33180
  • 73 + 33107 = 33180
  • 89 + 33091 = 33180
  • 97 + 33083 = 33180

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33180 first appears in π at position 77,331 of the decimal expansion (the 77,331ordinal-suffix:st 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.
