Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745942, here are decompositions:

  • 13 + 8745929 = 8745942
  • 19 + 8745923 = 8745942
  • 53 + 8745889 = 8745942
  • 61 + 8745881 = 8745942
  • 113 + 8745829 = 8745942
  • 193 + 8745749 = 8745942
  • 199 + 8745743 = 8745942
  • 239 + 8745703 = 8745942

Showing the first eight; more decompositions exist.
