Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025822, here are decompositions:

3 + 1025819 = 1025822
19 + 1025803 = 1025822
73 + 1025749 = 1025822
163 + 1025659 = 1025822
181 + 1025641 = 1025822
199 + 1025623 = 1025822
211 + 1025611 = 1025822
271 + 1025551 = 1025822

Showing the first eight; more decompositions exist.
