Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015378, here are decompositions:

11 + 1015367 = 1015378
17 + 1015361 = 1015378
29 + 1015349 = 1015378
101 + 1015277 = 1015378
179 + 1015199 = 1015378
239 + 1015139 = 1015378
251 + 1015127 = 1015378
281 + 1015097 = 1015378

Showing the first eight; more decompositions exist.
