Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015526, here are decompositions:

3 + 1015523 = 1015526
19 + 1015507 = 1015526
67 + 1015459 = 1015526
73 + 1015453 = 1015526
103 + 1015423 = 1015526
157 + 1015369 = 1015526
163 + 1015363 = 1015526
367 + 1015159 = 1015526

Showing the first eight; more decompositions exist.
