Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021634, here are decompositions:

7 + 1021627 = 1021634
13 + 1021621 = 1021634
73 + 1021561 = 1021634
151 + 1021483 = 1021634
193 + 1021441 = 1021634
307 + 1021327 = 1021634
331 + 1021303 = 1021634
337 + 1021297 = 1021634

Showing the first eight; more decompositions exist.
