Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37440, here are decompositions:

  • 17 + 37423 = 37440
  • 31 + 37409 = 37440
  • 43 + 37397 = 37440
  • 61 + 37379 = 37440
  • 71 + 37369 = 37440
  • 79 + 37361 = 37440
  • 83 + 37357 = 37440
  • 101 + 37339 = 37440

Showing the first eight; more decompositions exist.
