Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017806, here are decompositions:

7 + 1017799 = 1017806
19 + 1017787 = 1017806
103 + 1017703 = 1017806
157 + 1017649 = 1017806
193 + 1017613 = 1017806
199 + 1017607 = 1017806
367 + 1017439 = 1017806
487 + 1017319 = 1017806

Showing the first eight; more decompositions exist.
