Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625658, here are decompositions:

17 + 8625641 = 8625658
59 + 8625599 = 8625658
71 + 8625587 = 8625658
131 + 8625527 = 8625658
137 + 8625521 = 8625658
149 + 8625509 = 8625658
179 + 8625479 = 8625658
191 + 8625467 = 8625658

Showing the first eight; more decompositions exist.
