Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525908, here are decompositions:

  • 5 + 31525903 = 31525908
  • 17 + 31525891 = 31525908
  • 19 + 31525889 = 31525908
  • 59 + 31525849 = 31525908
  • 67 + 31525841 = 31525908
  • 97 + 31525811 = 31525908
  • 109 + 31525799 = 31525908
  • 131 + 31525777 = 31525908

Showing the first eight; more decompositions exist.
