Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012450, here are decompositions:

3 + 1012447 = 1012450
11 + 1012439 = 1012450
17 + 1012433 = 1012450
29 + 1012421 = 1012450
53 + 1012397 = 1012450
71 + 1012379 = 1012450
191 + 1012259 = 1012450
233 + 1012217 = 1012450

Showing the first eight; more decompositions exist.
