Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678042, here are decompositions:

  • 3 + 8678039 = 8678042
  • 13 + 8678029 = 8678042
  • 31 + 8678011 = 8678042
  • 151 + 8677891 = 8678042
  • 271 + 8677771 = 8678042
  • 283 + 8677759 = 8678042
  • 379 + 8677663 = 8678042
  • 643 + 8677399 = 8678042

Showing the first eight; more decompositions exist.
