Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016520, here are decompositions:

23 + 1016497 = 1016520
31 + 1016489 = 1016520
67 + 1016453 = 1016520
79 + 1016441 = 1016520
97 + 1016423 = 1016520
101 + 1016419 = 1016520
149 + 1016371 = 1016520
163 + 1016357 = 1016520

Showing the first eight; more decompositions exist.
