Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015886, here are decompositions:

43 + 1015843 = 1015886
73 + 1015813 = 1015886
139 + 1015747 = 1015886
163 + 1015723 = 1015886
283 + 1015603 = 1015886
337 + 1015549 = 1015886
379 + 1015507 = 1015886
433 + 1015453 = 1015886

Showing the first eight; more decompositions exist.
