Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625718, here are decompositions:

11 + 8625707 = 8625718
29 + 8625689 = 8625718
131 + 8625587 = 8625718
191 + 8625527 = 8625718
197 + 8625521 = 8625718
239 + 8625479 = 8625718
251 + 8625467 = 8625718
359 + 8625359 = 8625718

Showing the first eight; more decompositions exist.
