Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018632, here are decompositions:

11 + 1018621 = 1018632
19 + 1018613 = 1018632
73 + 1018559 = 1018632
89 + 1018543 = 1018632
193 + 1018439 = 1018632
211 + 1018421 = 1018632
331 + 1018301 = 1018632
379 + 1018253 = 1018632

Showing the first eight; more decompositions exist.
