Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677490, here are decompositions:

7 + 8677483 = 8677490
13 + 8677477 = 8677490
37 + 8677453 = 8677490
97 + 8677393 = 8677490
103 + 8677387 = 8677490
193 + 8677297 = 8677490
223 + 8677267 = 8677490
229 + 8677261 = 8677490

Showing the first eight; more decompositions exist.
