Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748778, here are decompositions:

  • 11 + 8748767 = 8748778
  • 47 + 8748731 = 8748778
  • 131 + 8748647 = 8748778
  • 179 + 8748599 = 8748778
  • 191 + 8748587 = 8748778
  • 197 + 8748581 = 8748778
  • 347 + 8748431 = 8748778
  • 359 + 8748419 = 8748778

Showing the first eight; more decompositions exist.
