Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574932, here are decompositions:

  • 5 + 31574927 = 31574932
  • 41 + 31574891 = 31574932
  • 71 + 31574861 = 31574932
  • 83 + 31574849 = 31574932
  • 239 + 31574693 = 31574932
  • 251 + 31574681 = 31574932
  • 293 + 31574639 = 31574932
  • 401 + 31574531 = 31574932

Showing the first eight; more decompositions exist.
