Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738628, here are decompositions:

  • 37 + 8738591 = 8738628
  • 47 + 8738581 = 8738628
  • 61 + 8738567 = 8738628
  • 89 + 8738539 = 8738628
  • 137 + 8738491 = 8738628
  • 179 + 8738449 = 8738628
  • 181 + 8738447 = 8738628
  • 191 + 8738437 = 8738628

Showing the first eight; more decompositions exist.
