Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625486, here are decompositions:

7 + 8625479 = 8625486
19 + 8625467 = 8625486
127 + 8625359 = 8625486
137 + 8625349 = 8625486
173 + 8625313 = 8625486
197 + 8625289 = 8625486
223 + 8625263 = 8625486
239 + 8625247 = 8625486

Showing the first eight; more decompositions exist.
