Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011638, here are decompositions:

7 + 1011631 = 1011638
37 + 1011601 = 1011638
79 + 1011559 = 1011638
241 + 1011397 = 1011638
307 + 1011331 = 1011638
349 + 1011289 = 1011638
367 + 1011271 = 1011638
409 + 1011229 = 1011638

Showing the first eight; more decompositions exist.
