Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748742, here are decompositions:

  • 3 + 8748739 = 8748742
  • 11 + 8748731 = 8748742
  • 29 + 8748713 = 8748742
  • 89 + 8748653 = 8748742
  • 179 + 8748563 = 8748742
  • 239 + 8748503 = 8748742
  • 269 + 8748473 = 8748742
  • 311 + 8748431 = 8748742

Showing the first eight; more decompositions exist.
