Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022472, here are decompositions:

5 + 1022467 = 1022472
23 + 1022449 = 1022472
29 + 1022443 = 1022472
43 + 1022429 = 1022472
83 + 1022389 = 1022472
89 + 1022383 = 1022472
131 + 1022341 = 1022472
181 + 1022291 = 1022472

Showing the first eight; more decompositions exist.
