Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031568, here are decompositions:

7 + 1031561 = 1031568
19 + 1031549 = 1031568
37 + 1031531 = 1031568
47 + 1031521 = 1031568
61 + 1031507 = 1031568
79 + 1031489 = 1031568
89 + 1031479 = 1031568
107 + 1031461 = 1031568

Showing the first eight; more decompositions exist.
