Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492, here are decompositions:

  • 5 + 487 = 492
  • 13 + 479 = 492
  • 29 + 463 = 492
  • 31 + 461 = 492
  • 43 + 449 = 492
  • 53 + 439 = 492
  • 59 + 433 = 492
  • 61 + 431 = 492

Showing the first eight; more decompositions exist.
