Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025450, here are decompositions:

7 + 1025443 = 1025450
31 + 1025419 = 1025450
37 + 1025413 = 1025450
43 + 1025407 = 1025450
67 + 1025383 = 1025450
103 + 1025347 = 1025450
193 + 1025257 = 1025450
211 + 1025239 = 1025450

Showing the first eight; more decompositions exist.
