Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625624, here are decompositions:

37 + 8625587 = 8625624
71 + 8625553 = 8625624
83 + 8625541 = 8625624
97 + 8625527 = 8625624
103 + 8625521 = 8625624
107 + 8625517 = 8625624
131 + 8625493 = 8625624
157 + 8625467 = 8625624

Showing the first eight; more decompositions exist.
