Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640590, here are decompositions:

3 + 8640587 = 8640590
31 + 8640559 = 8640590
37 + 8640553 = 8640590
43 + 8640547 = 8640590
97 + 8640493 = 8640590
109 + 8640481 = 8640590
139 + 8640451 = 8640590
151 + 8640439 = 8640590

Showing the first eight; more decompositions exist.
