Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045450, here are decompositions:

23 + 1045427 = 1045450
41 + 1045409 = 1045450
53 + 1045397 = 1045450
59 + 1045391 = 1045450
83 + 1045367 = 1045450
101 + 1045349 = 1045450
173 + 1045277 = 1045450
227 + 1045223 = 1045450

Showing the first eight; more decompositions exist.
