Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625386, here are decompositions:

37 + 8625349 = 8625386
43 + 8625343 = 8625386
73 + 8625313 = 8625386
97 + 8625289 = 8625386
139 + 8625247 = 8625386
157 + 8625229 = 8625386
199 + 8625187 = 8625386
313 + 8625073 = 8625386

Showing the first eight; more decompositions exist.
