Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29812, here are decompositions:

  • 23 + 29789 = 29812
  • 53 + 29759 = 29812
  • 59 + 29753 = 29812
  • 71 + 29741 = 29812
  • 89 + 29723 = 29812
  • 149 + 29663 = 29812
  • 179 + 29633 = 29812
  • 239 + 29573 = 29812

Showing the first eight; more decompositions exist.
