Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031572, here are decompositions:

11 + 1031561 = 1031572
23 + 1031549 = 1031572
41 + 1031531 = 1031572
83 + 1031489 = 1031572
89 + 1031483 = 1031572
149 + 1031423 = 1031572
173 + 1031399 = 1031572
263 + 1031309 = 1031572

Showing the first eight; more decompositions exist.
