Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021312, here are decompositions:

11 + 1021301 = 1021312
23 + 1021289 = 1021312
29 + 1021283 = 1021312
41 + 1021271 = 1021312
53 + 1021259 = 1021312
59 + 1021253 = 1021312
113 + 1021199 = 1021312
239 + 1021073 = 1021312

Showing the first eight; more decompositions exist.
