Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021308, here are decompositions:

5 + 1021303 = 1021308
7 + 1021301 = 1021308
11 + 1021297 = 1021308
17 + 1021291 = 1021308
19 + 1021289 = 1021308
37 + 1021271 = 1021308
47 + 1021261 = 1021308
109 + 1021199 = 1021308

Showing the first eight; more decompositions exist.
