Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618490, here are decompositions:

7 + 8618483 = 8618490
11 + 8618479 = 8618490
47 + 8618443 = 8618490
61 + 8618429 = 8618490
103 + 8618387 = 8618490
113 + 8618377 = 8618490
151 + 8618339 = 8618490
163 + 8618327 = 8618490

Showing the first eight; more decompositions exist.
