Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057442, here are decompositions:

31 + 1057411 = 1057442
151 + 1057291 = 1057442
163 + 1057279 = 1057442
193 + 1057249 = 1057442
223 + 1057219 = 1057442
313 + 1057129 = 1057442
349 + 1057093 = 1057442
409 + 1057033 = 1057442

Showing the first eight; more decompositions exist.
