Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015428, here are decompositions:

5 + 1015423 = 1015428
19 + 1015409 = 1015428
59 + 1015369 = 1015428
61 + 1015367 = 1015428
67 + 1015361 = 1015428
79 + 1015349 = 1015428
151 + 1015277 = 1015428
229 + 1015199 = 1015428

Showing the first eight; more decompositions exist.
