Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031442, here are decompositions:

11 + 1031431 = 1031442
19 + 1031423 = 1031442
29 + 1031413 = 1031442
31 + 1031411 = 1031442
43 + 1031399 = 1031442
151 + 1031291 = 1031442
163 + 1031279 = 1031442
211 + 1031231 = 1031442

Showing the first eight; more decompositions exist.
