Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031488, here are decompositions:

5 + 1031483 = 1031488
11 + 1031477 = 1031488
41 + 1031447 = 1031488
89 + 1031399 = 1031488
131 + 1031357 = 1031488
179 + 1031309 = 1031488
197 + 1031291 = 1031488
257 + 1031231 = 1031488

Showing the first eight; more decompositions exist.
