Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031286, here are decompositions:

5 + 1031281 = 1031286
7 + 1031279 = 1031286
19 + 1031267 = 1031286
97 + 1031189 = 1031286
149 + 1031137 = 1031286
167 + 1031119 = 1031286
229 + 1031057 = 1031286
233 + 1031053 = 1031286

Showing the first eight; more decompositions exist.
