Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015818, here are decompositions:

5 + 1015813 = 1015818
71 + 1015747 = 1015818
79 + 1015739 = 1015818
109 + 1015709 = 1015818
127 + 1015691 = 1015818
157 + 1015661 = 1015818
191 + 1015627 = 1015818
257 + 1015561 = 1015818

Showing the first eight; more decompositions exist.
