Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015874, here are decompositions:

3 + 1015871 = 1015874
31 + 1015843 = 1015874
61 + 1015813 = 1015874
127 + 1015747 = 1015874
151 + 1015723 = 1015874
271 + 1015603 = 1015874
313 + 1015561 = 1015874
367 + 1015507 = 1015874

Showing the first eight; more decompositions exist.
