Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013638, here are decompositions:

11 + 1013627 = 1013638
29 + 1013609 = 1013638
107 + 1013531 = 1013638
137 + 1013501 = 1013638
167 + 1013471 = 1013638
239 + 1013399 = 1013638
317 + 1013321 = 1013638
347 + 1013291 = 1013638

Showing the first eight; more decompositions exist.
