Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716778, here are decompositions:

19 + 8716759 = 8716778
139 + 8716639 = 8716778
151 + 8716627 = 8716778
199 + 8716579 = 8716778
211 + 8716567 = 8716778
331 + 8716447 = 8716778
337 + 8716441 = 8716778
349 + 8716429 = 8716778

Showing the first eight; more decompositions exist.
