Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525938, here are decompositions:

  • 11 + 31525927 = 31525938
  • 19 + 31525919 = 31525938
  • 29 + 31525909 = 31525938
  • 47 + 31525891 = 31525938
  • 89 + 31525849 = 31525938
  • 97 + 31525841 = 31525938
  • 127 + 31525811 = 31525938
  • 139 + 31525799 = 31525938

Showing the first eight; more decompositions exist.
