Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541870, here are decompositions:

  • 13 + 31541857 = 31541870
  • 43 + 31541827 = 31541870
  • 109 + 31541761 = 31541870
  • 163 + 31541707 = 31541870
  • 193 + 31541677 = 31541870
  • 211 + 31541659 = 31541870
  • 307 + 31541563 = 31541870
  • 313 + 31541557 = 31541870

Showing the first eight; more decompositions exist.
