Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021586, here are decompositions:

103 + 1021483 = 1021586
157 + 1021429 = 1021586
199 + 1021387 = 1021586
283 + 1021303 = 1021586
457 + 1021129 = 1021586
463 + 1021123 = 1021586
499 + 1021087 = 1021586
607 + 1020979 = 1021586

Showing the first eight; more decompositions exist.
