Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015480, here are decompositions:

17 + 1015463 = 1015480
29 + 1015451 = 1015480
47 + 1015433 = 1015480
71 + 1015409 = 1015480
113 + 1015367 = 1015480
131 + 1015349 = 1015480
281 + 1015199 = 1015480
317 + 1015163 = 1015480

Showing the first eight; more decompositions exist.
