Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031542, here are decompositions:

11 + 1031531 = 1031542
53 + 1031489 = 1031542
59 + 1031483 = 1031542
131 + 1031411 = 1031542
233 + 1031309 = 1031542
251 + 1031291 = 1031542
263 + 1031279 = 1031542
311 + 1031231 = 1031542

Showing the first eight; more decompositions exist.
