Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609490, here are decompositions:

7 + 8609483 = 8609490
13 + 8609477 = 8609490
17 + 8609473 = 8609490
31 + 8609459 = 8609490
41 + 8609449 = 8609490
47 + 8609443 = 8609490
59 + 8609431 = 8609490
79 + 8609411 = 8609490

Showing the first eight; more decompositions exist.
