Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643590, here are decompositions:

3 + 8643587 = 8643590
13 + 8643577 = 8643590
103 + 8643487 = 8643590
157 + 8643433 = 8643590
181 + 8643409 = 8643590
223 + 8643367 = 8643590
283 + 8643307 = 8643590
367 + 8643223 = 8643590

Showing the first eight; more decompositions exist.
