Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039638, here are decompositions:

7 + 1039631 = 1039638
31 + 1039607 = 1039638
101 + 1039537 = 1039638
157 + 1039481 = 1039638
211 + 1039427 = 1039638
251 + 1039387 = 1039638
311 + 1039327 = 1039638
317 + 1039321 = 1039638

Showing the first eight; more decompositions exist.
