Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625986, here are decompositions:

3 + 8625983 = 8625986
7 + 8625979 = 8625986
13 + 8625973 = 8625986
73 + 8625913 = 8625986
97 + 8625889 = 8625986
199 + 8625787 = 8625986
277 + 8625709 = 8625986
337 + 8625649 = 8625986

Showing the first eight; more decompositions exist.
