Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625860, here are decompositions:

7 + 8625853 = 8625860
73 + 8625787 = 8625860
127 + 8625733 = 8625860
151 + 8625709 = 8625860
211 + 8625649 = 8625860
223 + 8625637 = 8625860
307 + 8625553 = 8625860
367 + 8625493 = 8625860

Showing the first eight; more decompositions exist.
