Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36640, here are decompositions:

  • 3 + 36637 = 36640
  • 11 + 36629 = 36640
  • 41 + 36599 = 36640
  • 53 + 36587 = 36640
  • 89 + 36551 = 36640
  • 113 + 36527 = 36640
  • 167 + 36473 = 36640
  • 173 + 36467 = 36640

Showing the first eight; more decompositions exist.
