Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997742, here are decompositions:

  • 3 + 997739 = 997742
  • 43 + 997699 = 997742
  • 61 + 997681 = 997742
  • 79 + 997663 = 997742
  • 373 + 997369 = 997742
  • 409 + 997333 = 997742
  • 433 + 997309 = 997742
  • 463 + 997279 = 997742

Showing the first eight; more decompositions exist.
