Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015812, here are decompositions:

43 + 1015769 = 1015812
59 + 1015753 = 1015812
73 + 1015739 = 1015812
89 + 1015723 = 1015812
103 + 1015709 = 1015812
151 + 1015661 = 1015812
211 + 1015601 = 1015812
241 + 1015571 = 1015812

Showing the first eight; more decompositions exist.
