Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625228, here are decompositions:

37 + 8625191 = 8625228
41 + 8625187 = 8625228
97 + 8625131 = 8625228
107 + 8625121 = 8625228
109 + 8625119 = 8625228
137 + 8625091 = 8625228
151 + 8625077 = 8625228
229 + 8624999 = 8625228

Showing the first eight; more decompositions exist.
