Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625620, here are decompositions:

61 + 8625559 = 8625620
67 + 8625553 = 8625620
79 + 8625541 = 8625620
103 + 8625517 = 8625620
127 + 8625493 = 8625620
271 + 8625349 = 8625620
277 + 8625343 = 8625620
307 + 8625313 = 8625620

Showing the first eight; more decompositions exist.
