Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015540, here are decompositions:

17 + 1015523 = 1015540
23 + 1015517 = 1015540
41 + 1015499 = 1015540
59 + 1015481 = 1015540
89 + 1015451 = 1015540
107 + 1015433 = 1015540
131 + 1015409 = 1015540
137 + 1015403 = 1015540

Showing the first eight; more decompositions exist.
