Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015826, here are decompositions:

3 + 1015823 = 1015826
13 + 1015813 = 1015826
73 + 1015753 = 1015826
79 + 1015747 = 1015826
103 + 1015723 = 1015826
199 + 1015627 = 1015826
223 + 1015603 = 1015826
277 + 1015549 = 1015826

Showing the first eight; more decompositions exist.
