Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021716, here are decompositions:

5 + 1021711 = 1021716
19 + 1021697 = 1021716
43 + 1021673 = 1021716
53 + 1021663 = 1021716
89 + 1021627 = 1021716
139 + 1021577 = 1021716
229 + 1021487 = 1021716
233 + 1021483 = 1021716

Showing the first eight; more decompositions exist.
