Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626490, here are decompositions:

3 + 8626487 = 8626490
31 + 8626459 = 8626490
73 + 8626417 = 8626490
193 + 8626297 = 8626490
241 + 8626249 = 8626490
331 + 8626159 = 8626490
349 + 8626141 = 8626490
577 + 8625913 = 8626490

Showing the first eight; more decompositions exist.
