Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499252, here are decompositions:

  • 13 + 31499239 = 31499252
  • 229 + 31499023 = 31499252
  • 373 + 31498879 = 31499252
  • 439 + 31498813 = 31499252
  • 613 + 31498639 = 31499252
  • 661 + 31498591 = 31499252
  • 739 + 31498513 = 31499252
  • 1039 + 31498213 = 31499252

Showing the first eight; more decompositions exist.
