Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659490, here are decompositions:

19 + 8659471 = 8659490
67 + 8659423 = 8659490
97 + 8659393 = 8659490
109 + 8659381 = 8659490
127 + 8659363 = 8659490
139 + 8659351 = 8659490
181 + 8659309 = 8659490
211 + 8659279 = 8659490

Showing the first eight; more decompositions exist.
