Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625648, here are decompositions:

7 + 8625641 = 8625648
11 + 8625637 = 8625648
61 + 8625587 = 8625648
89 + 8625559 = 8625648
107 + 8625541 = 8625648
127 + 8625521 = 8625648
131 + 8625517 = 8625648
139 + 8625509 = 8625648

Showing the first eight; more decompositions exist.
