Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040450, here are decompositions:

3 + 1040447 = 1040450
31 + 1040419 = 1040450
43 + 1040407 = 1040450
79 + 1040371 = 1040450
97 + 1040353 = 1040450
139 + 1040311 = 1040450
223 + 1040227 = 1040450
283 + 1040167 = 1040450

Showing the first eight; more decompositions exist.
