Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79220, here are decompositions:

  • 19 + 79201 = 79220
  • 61 + 79159 = 79220
  • 67 + 79153 = 79220
  • 73 + 79147 = 79220
  • 109 + 79111 = 79220
  • 157 + 79063 = 79220
  • 181 + 79039 = 79220
  • 241 + 78979 = 79220

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 79220 first appears in π at position 40,018 of the decimal expansion (the 40,018ordinal-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.
