Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017886, here are decompositions:

5 + 1017881 = 1017886
29 + 1017857 = 1017886
59 + 1017827 = 1017886
137 + 1017749 = 1017886
167 + 1017719 = 1017886
173 + 1017713 = 1017886
239 + 1017647 = 1017886
263 + 1017623 = 1017886

Showing the first eight; more decompositions exist.
