Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625788, here are decompositions:

79 + 8625709 = 8625788
139 + 8625649 = 8625788
151 + 8625637 = 8625788
229 + 8625559 = 8625788
271 + 8625517 = 8625788
337 + 8625451 = 8625788
439 + 8625349 = 8625788
487 + 8625301 = 8625788

Showing the first eight; more decompositions exist.
