Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020450, here are decompositions:

19 + 1020431 = 1020450
31 + 1020419 = 1020450
37 + 1020413 = 1020450
43 + 1020407 = 1020450
61 + 1020389 = 1020450
71 + 1020379 = 1020450
89 + 1020361 = 1020450
97 + 1020353 = 1020450

Showing the first eight; more decompositions exist.
