Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625222, here are decompositions:

19 + 8625203 = 8625222
31 + 8625191 = 8625222
101 + 8625121 = 8625222
103 + 8625119 = 8625222
131 + 8625091 = 8625222
139 + 8625083 = 8625222
149 + 8625073 = 8625222
163 + 8625059 = 8625222

Showing the first eight; more decompositions exist.
