Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472832, here are decompositions:

  • 5 + 31472827 = 31472832
  • 19 + 31472813 = 31472832
  • 59 + 31472773 = 31472832
  • 109 + 31472723 = 31472832
  • 163 + 31472669 = 31472832
  • 199 + 31472633 = 31472832
  • 241 + 31472591 = 31472832
  • 331 + 31472501 = 31472832

Showing the first eight; more decompositions exist.
