Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029638, here are decompositions:

37 + 1029601 = 1029638
61 + 1029577 = 1029638
139 + 1029499 = 1029638
151 + 1029487 = 1029638
157 + 1029481 = 1029638
229 + 1029409 = 1029638
277 + 1029361 = 1029638
307 + 1029331 = 1029638

Showing the first eight; more decompositions exist.
