Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017880, here are decompositions:

23 + 1017857 = 1017880
29 + 1017851 = 1017880
53 + 1017827 = 1017880
131 + 1017749 = 1017880
167 + 1017713 = 1017880
197 + 1017683 = 1017880
233 + 1017647 = 1017880
257 + 1017623 = 1017880

Showing the first eight; more decompositions exist.
