Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015488, here are decompositions:

7 + 1015481 = 1015488
17 + 1015471 = 1015488
29 + 1015459 = 1015488
37 + 1015451 = 1015488
79 + 1015409 = 1015488
127 + 1015361 = 1015488
139 + 1015349 = 1015488
179 + 1015309 = 1015488

Showing the first eight; more decompositions exist.
