Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015486, here are decompositions:

5 + 1015481 = 1015486
23 + 1015463 = 1015486
53 + 1015433 = 1015486
83 + 1015403 = 1015486
137 + 1015349 = 1015486
347 + 1015139 = 1015486
359 + 1015127 = 1015486
389 + 1015097 = 1015486

Showing the first eight; more decompositions exist.
