Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045222, here are decompositions:

23 + 1045199 = 1045222
29 + 1045193 = 1045222
71 + 1045151 = 1045222
179 + 1045043 = 1045222
251 + 1044971 = 1045222
281 + 1044941 = 1045222
383 + 1044839 = 1045222
389 + 1044833 = 1045222

Showing the first eight; more decompositions exist.
