Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529874, here are decompositions:

  • 31 + 31529843 = 31529874
  • 157 + 31529717 = 31529874
  • 193 + 31529681 = 31529874
  • 197 + 31529677 = 31529874
  • 223 + 31529651 = 31529874
  • 251 + 31529623 = 31529874
  • 281 + 31529593 = 31529874
  • 307 + 31529567 = 31529874

Showing the first eight; more decompositions exist.
