Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634680, here are decompositions:

3 + 8634677 = 8634680
13 + 8634667 = 8634680
163 + 8634517 = 8634680
199 + 8634481 = 8634680
211 + 8634469 = 8634680
283 + 8634397 = 8634680
421 + 8634259 = 8634680
541 + 8634139 = 8634680

Showing the first eight; more decompositions exist.
