Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525950, here are decompositions:

  • 23 + 31525927 = 31525950
  • 31 + 31525919 = 31525950
  • 37 + 31525913 = 31525950
  • 41 + 31525909 = 31525950
  • 47 + 31525903 = 31525950
  • 59 + 31525891 = 31525950
  • 61 + 31525889 = 31525950
  • 101 + 31525849 = 31525950

Showing the first eight; more decompositions exist.
