Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625650, here are decompositions:

13 + 8625637 = 8625650
97 + 8625553 = 8625650
109 + 8625541 = 8625650
157 + 8625493 = 8625650
199 + 8625451 = 8625650
307 + 8625343 = 8625650
337 + 8625313 = 8625650
349 + 8625301 = 8625650

Showing the first eight; more decompositions exist.
