Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758728, here are decompositions:

7 + 8758721 = 8758728
31 + 8758697 = 8758728
59 + 8758669 = 8758728
67 + 8758661 = 8758728
131 + 8758597 = 8758728
151 + 8758577 = 8758728
179 + 8758549 = 8758728
191 + 8758537 = 8758728

Showing the first eight; more decompositions exist.
