Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598152, here are decompositions:

  • 11 + 31598141 = 31598152
  • 191 + 31597961 = 31598152
  • 239 + 31597913 = 31598152
  • 359 + 31597793 = 31598152
  • 389 + 31597763 = 31598152
  • 431 + 31597721 = 31598152
  • 479 + 31597673 = 31598152
  • 659 + 31597493 = 31598152

Showing the first eight; more decompositions exist.
