Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021678, here are decompositions:

5 + 1021673 = 1021678
17 + 1021661 = 1021678
101 + 1021577 = 1021678
107 + 1021571 = 1021678
137 + 1021541 = 1021678
191 + 1021487 = 1021678
311 + 1021367 = 1021678
347 + 1021331 = 1021678

Showing the first eight; more decompositions exist.
