Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031690, here are decompositions:

13 + 1031677 = 1031690
61 + 1031629 = 1031690
67 + 1031623 = 1031690
97 + 1031593 = 1031690
157 + 1031533 = 1031690
211 + 1031479 = 1031690
229 + 1031461 = 1031690
277 + 1031413 = 1031690

Showing the first eight; more decompositions exist.
