Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031566, here are decompositions:

5 + 1031561 = 1031566
17 + 1031549 = 1031566
59 + 1031507 = 1031566
83 + 1031483 = 1031566
89 + 1031477 = 1031566
167 + 1031399 = 1031566
257 + 1031309 = 1031566
449 + 1031117 = 1031566

Showing the first eight; more decompositions exist.
