Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 462, here are decompositions:

  • 5 + 457 = 462
  • 13 + 449 = 462
  • 19 + 443 = 462
  • 23 + 439 = 462
  • 29 + 433 = 462
  • 31 + 431 = 462
  • 41 + 421 = 462
  • 43 + 419 = 462

Showing the first eight; more decompositions exist.
