Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627778, here are decompositions:

37 + 8627741 = 8627778
79 + 8627699 = 8627778
97 + 8627681 = 8627778
139 + 8627639 = 8627778
151 + 8627627 = 8627778
167 + 8627611 = 8627778
197 + 8627581 = 8627778
251 + 8627527 = 8627778

Showing the first eight; more decompositions exist.
