Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015672, here are decompositions:

11 + 1015661 = 1015672
71 + 1015601 = 1015672
101 + 1015571 = 1015672
113 + 1015559 = 1015672
131 + 1015541 = 1015672
149 + 1015523 = 1015672
173 + 1015499 = 1015672
191 + 1015481 = 1015672

Showing the first eight; more decompositions exist.
