Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627782, here are decompositions:

5 + 8627777 = 8627782
41 + 8627741 = 8627782
83 + 8627699 = 8627782
89 + 8627693 = 8627782
101 + 8627681 = 8627782
173 + 8627609 = 8627782
179 + 8627603 = 8627782
269 + 8627513 = 8627782

Showing the first eight; more decompositions exist.
