Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021974, here are decompositions:

11 + 1021963 = 1021974
13 + 1021961 = 1021974
67 + 1021907 = 1021974
113 + 1021861 = 1021974
137 + 1021837 = 1021974
167 + 1021807 = 1021974
181 + 1021793 = 1021974
197 + 1021777 = 1021974

Showing the first eight; more decompositions exist.
