Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052638, here are decompositions:

29 + 1052609 = 1052638
71 + 1052567 = 1052638
101 + 1052537 = 1052638
107 + 1052531 = 1052638
149 + 1052489 = 1052638
179 + 1052459 = 1052638
311 + 1052327 = 1052638
317 + 1052321 = 1052638

Showing the first eight; more decompositions exist.
