Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640612, here are decompositions:

11 + 8640601 = 8640612
53 + 8640559 = 8640612
59 + 8640553 = 8640612
109 + 8640503 = 8640612
131 + 8640481 = 8640612
173 + 8640439 = 8640612
193 + 8640419 = 8640612
263 + 8640349 = 8640612

Showing the first eight; more decompositions exist.
