Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625992, here are decompositions:

  • 5 + 31625987 = 31625992
  • 11 + 31625981 = 31625992
  • 23 + 31625969 = 31625992
  • 29 + 31625963 = 31625992
  • 53 + 31625939 = 31625992
  • 149 + 31625843 = 31625992
  • 173 + 31625819 = 31625992
  • 239 + 31625753 = 31625992

Showing the first eight; more decompositions exist.
