Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529138, here are decompositions:

  • 31 + 31529107 = 31529138
  • 229 + 31528909 = 31529138
  • 307 + 31528831 = 31529138
  • 331 + 31528807 = 31529138
  • 337 + 31528801 = 31529138
  • 397 + 31528741 = 31529138
  • 409 + 31528729 = 31529138
  • 607 + 31528531 = 31529138

Showing the first eight; more decompositions exist.
