Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017866, here are decompositions:

7 + 1017859 = 1017866
19 + 1017847 = 1017866
67 + 1017799 = 1017866
79 + 1017787 = 1017866
163 + 1017703 = 1017866
193 + 1017673 = 1017866
307 + 1017559 = 1017866
313 + 1017553 = 1017866

Showing the first eight; more decompositions exist.
