Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625764, here are decompositions:

31 + 8625733 = 8625764
127 + 8625637 = 8625764
211 + 8625553 = 8625764
223 + 8625541 = 8625764
271 + 8625493 = 8625764
313 + 8625451 = 8625764
421 + 8625343 = 8625764
463 + 8625301 = 8625764

Showing the first eight; more decompositions exist.
