Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031638, here are decompositions:

5 + 1031633 = 1031638
29 + 1031609 = 1031638
89 + 1031549 = 1031638
107 + 1031531 = 1031638
131 + 1031507 = 1031638
149 + 1031489 = 1031638
191 + 1031447 = 1031638
227 + 1031411 = 1031638

Showing the first eight; more decompositions exist.
