Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031886, here are decompositions:

17 + 1031869 = 1031886
73 + 1031813 = 1031886
127 + 1031759 = 1031886
157 + 1031729 = 1031886
179 + 1031707 = 1031886
257 + 1031629 = 1031886
263 + 1031623 = 1031886
277 + 1031609 = 1031886

Showing the first eight; more decompositions exist.
