Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023450, here are decompositions:

31 + 1023419 = 1023450
37 + 1023413 = 1023450
41 + 1023409 = 1023450
59 + 1023391 = 1023450
61 + 1023389 = 1023450
83 + 1023367 = 1023450
89 + 1023361 = 1023450
97 + 1023353 = 1023450

Showing the first eight; more decompositions exist.
