Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049638, here are decompositions:

89 + 1049549 = 1049638
101 + 1049537 = 1049638
167 + 1049471 = 1049638
179 + 1049459 = 1049638
251 + 1049387 = 1049638
419 + 1049219 = 1049638
461 + 1049177 = 1049638
467 + 1049171 = 1049638

Showing the first eight; more decompositions exist.
