Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574544, here are decompositions:

  • 13 + 31574531 = 31574544
  • 37 + 31574507 = 31574544
  • 47 + 31574497 = 31574544
  • 101 + 31574443 = 31574544
  • 107 + 31574437 = 31574544
  • 181 + 31574363 = 31574544
  • 241 + 31574303 = 31574544
  • 283 + 31574261 = 31574544

Showing the first eight; more decompositions exist.
