Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740490, here are decompositions:

  • 37 + 8740453 = 8740490
  • 43 + 8740447 = 8740490
  • 61 + 8740429 = 8740490
  • 79 + 8740411 = 8740490
  • 97 + 8740393 = 8740490
  • 103 + 8740387 = 8740490
  • 163 + 8740327 = 8740490
  • 271 + 8740219 = 8740490

Showing the first eight; more decompositions exist.
