Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015492, here are decompositions:

11 + 1015481 = 1015492
29 + 1015463 = 1015492
41 + 1015451 = 1015492
59 + 1015433 = 1015492
83 + 1015409 = 1015492
89 + 1015403 = 1015492
131 + 1015361 = 1015492
293 + 1015199 = 1015492

Showing the first eight; more decompositions exist.
