Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015380, here are decompositions:

11 + 1015369 = 1015380
13 + 1015367 = 1015380
17 + 1015363 = 1015380
19 + 1015361 = 1015380
31 + 1015349 = 1015380
71 + 1015309 = 1015380
103 + 1015277 = 1015380
173 + 1015207 = 1015380

Showing the first eight; more decompositions exist.
