Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031816, here are decompositions:

3 + 1031813 = 1031816
7 + 1031809 = 1031816
109 + 1031707 = 1031816
139 + 1031677 = 1031816
193 + 1031623 = 1031816
223 + 1031593 = 1031816
283 + 1031533 = 1031816
337 + 1031479 = 1031816

Showing the first eight; more decompositions exist.
