Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494842, here are decompositions:

  • 53 + 494789 = 494842
  • 59 + 494783 = 494842
  • 83 + 494759 = 494842
  • 149 + 494693 = 494842
  • 191 + 494651 = 494842
  • 233 + 494609 = 494842
  • 251 + 494591 = 494842
  • 281 + 494561 = 494842

Showing the first eight; more decompositions exist.
