Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021624, here are decompositions:

3 + 1021621 = 1021624
47 + 1021577 = 1021624
53 + 1021571 = 1021624
83 + 1021541 = 1021624
137 + 1021487 = 1021624
167 + 1021457 = 1021624
251 + 1021373 = 1021624
257 + 1021367 = 1021624

Showing the first eight; more decompositions exist.
