Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33580840, here are decompositions:

  • 53 + 33580787 = 33580840
  • 71 + 33580769 = 33580840
  • 113 + 33580727 = 33580840
  • 131 + 33580709 = 33580840
  • 197 + 33580643 = 33580840
  • 317 + 33580523 = 33580840
  • 353 + 33580487 = 33580840
  • 443 + 33580397 = 33580840

Showing the first eight; more decompositions exist.
