Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992640, here are decompositions:

  • 7 + 992633 = 992640
  • 17 + 992623 = 992640
  • 31 + 992609 = 992640
  • 37 + 992603 = 992640
  • 79 + 992561 = 992640
  • 101 + 992539 = 992640
  • 127 + 992513 = 992640
  • 179 + 992461 = 992640

Showing the first eight; more decompositions exist.
