Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045646, here are decompositions:

3 + 1045643 = 1045646
13 + 1045633 = 1045646
73 + 1045573 = 1045646
97 + 1045549 = 1045646
103 + 1045543 = 1045646
139 + 1045507 = 1045646
223 + 1045423 = 1045646
337 + 1045309 = 1045646

Showing the first eight; more decompositions exist.
