Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625722, here are decompositions:

13 + 8625709 = 8625722
73 + 8625649 = 8625722
163 + 8625559 = 8625722
181 + 8625541 = 8625722
229 + 8625493 = 8625722
271 + 8625451 = 8625722
373 + 8625349 = 8625722
379 + 8625343 = 8625722

Showing the first eight; more decompositions exist.
