Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015422, here are decompositions:

13 + 1015409 = 1015422
19 + 1015403 = 1015422
53 + 1015369 = 1015422
59 + 1015363 = 1015422
61 + 1015361 = 1015422
73 + 1015349 = 1015422
113 + 1015309 = 1015422
223 + 1015199 = 1015422

Showing the first eight; more decompositions exist.
