Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706778, here are decompositions:

71 + 8706707 = 8706778
107 + 8706671 = 8706778
131 + 8706647 = 8706778
167 + 8706611 = 8706778
191 + 8706587 = 8706778
251 + 8706527 = 8706778
281 + 8706497 = 8706778
317 + 8706461 = 8706778

Showing the first eight; more decompositions exist.
