Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510050, here are decompositions:

  • 29 + 31510021 = 31510050
  • 41 + 31510009 = 31510050
  • 43 + 31510007 = 31510050
  • 59 + 31509991 = 31510050
  • 79 + 31509971 = 31510050
  • 83 + 31509967 = 31510050
  • 101 + 31509949 = 31510050
  • 109 + 31509941 = 31510050

Showing the first eight; more decompositions exist.
