Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662490, here are decompositions:

3 + 8662487 = 8662490
7 + 8662483 = 8662490
19 + 8662471 = 8662490
37 + 8662453 = 8662490
43 + 8662447 = 8662490
79 + 8662411 = 8662490
163 + 8662327 = 8662490
211 + 8662279 = 8662490

Showing the first eight; more decompositions exist.
