Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532698, here are decompositions:

  • 5 + 31532693 = 31532698
  • 11 + 31532687 = 31532698
  • 59 + 31532639 = 31532698
  • 101 + 31532597 = 31532698
  • 191 + 31532507 = 31532698
  • 269 + 31532429 = 31532698
  • 359 + 31532339 = 31532698
  • 419 + 31532279 = 31532698

Showing the first eight; more decompositions exist.
