Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021320, here are decompositions:

17 + 1021303 = 1021320
19 + 1021301 = 1021320
23 + 1021297 = 1021320
29 + 1021291 = 1021320
31 + 1021289 = 1021320
37 + 1021283 = 1021320
59 + 1021261 = 1021320
61 + 1021259 = 1021320

Showing the first eight; more decompositions exist.
