Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619584, here are decompositions:

  • 23 + 31619561 = 31619584
  • 41 + 31619543 = 31619584
  • 53 + 31619531 = 31619584
  • 83 + 31619501 = 31619584
  • 197 + 31619387 = 31619584
  • 257 + 31619327 = 31619584
  • 317 + 31619267 = 31619584
  • 401 + 31619183 = 31619584

Showing the first eight; more decompositions exist.
