Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021630, here are decompositions:

3 + 1021627 = 1021630
53 + 1021577 = 1021630
59 + 1021571 = 1021630
89 + 1021541 = 1021630
167 + 1021463 = 1021630
173 + 1021457 = 1021630
227 + 1021403 = 1021630
257 + 1021373 = 1021630

Showing the first eight; more decompositions exist.
