Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625982, here are decompositions:

3 + 8625979 = 8625982
23 + 8625959 = 8625982
149 + 8625833 = 8625982
173 + 8625809 = 8625982
293 + 8625689 = 8625982
383 + 8625599 = 8625982
461 + 8625521 = 8625982
503 + 8625479 = 8625982

Showing the first eight; more decompositions exist.
