Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74040, here are decompositions:

  • 13 + 74027 = 74040
  • 19 + 74021 = 74040
  • 23 + 74017 = 74040
  • 41 + 73999 = 74040
  • 67 + 73973 = 74040
  • 79 + 73961 = 74040
  • 89 + 73951 = 74040
  • 97 + 73943 = 74040

Showing the first eight; more decompositions exist.
