Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625424, here are decompositions:

107 + 8625317 = 8625424
113 + 8625311 = 8625424
191 + 8625233 = 8625424
233 + 8625191 = 8625424
251 + 8625173 = 8625424
293 + 8625131 = 8625424
347 + 8625077 = 8625424
443 + 8624981 = 8625424

Showing the first eight; more decompositions exist.
