Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017790, here are decompositions:

3 + 1017787 = 1017790
41 + 1017749 = 1017790
71 + 1017719 = 1017790
107 + 1017683 = 1017790
167 + 1017623 = 1017790
173 + 1017617 = 1017790
239 + 1017551 = 1017790
251 + 1017539 = 1017790

Showing the first eight; more decompositions exist.
