Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625156, here are decompositions:

37 + 8625119 = 8625156
73 + 8625083 = 8625156
79 + 8625077 = 8625156
83 + 8625073 = 8625156
97 + 8625059 = 8625156
103 + 8625053 = 8625156
149 + 8625007 = 8625156
157 + 8624999 = 8625156

Showing the first eight; more decompositions exist.
