Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588814, here are decompositions:

  • 7 + 31588807 = 31588814
  • 157 + 31588657 = 31588814
  • 211 + 31588603 = 31588814
  • 331 + 31588483 = 31588814
  • 373 + 31588441 = 31588814
  • 457 + 31588357 = 31588814
  • 463 + 31588351 = 31588814
  • 547 + 31588267 = 31588814

Showing the first eight; more decompositions exist.
