Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015456, here are decompositions:

3 + 1015453 = 1015456
5 + 1015451 = 1015456
23 + 1015433 = 1015456
47 + 1015409 = 1015456
53 + 1015403 = 1015456
89 + 1015367 = 1015456
107 + 1015349 = 1015456
179 + 1015277 = 1015456

Showing the first eight; more decompositions exist.
