Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018826, here are decompositions:

13 + 1018813 = 1018826
19 + 1018807 = 1018826
37 + 1018789 = 1018826
97 + 1018729 = 1018826
157 + 1018669 = 1018826
283 + 1018543 = 1018826
313 + 1018513 = 1018826
337 + 1018489 = 1018826

Showing the first eight; more decompositions exist.
