Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045228, here are decompositions:

5 + 1045223 = 1045228
29 + 1045199 = 1045228
71 + 1045157 = 1045228
167 + 1045061 = 1045228
257 + 1044971 = 1045228
389 + 1044839 = 1045228
419 + 1044809 = 1045228
449 + 1044779 = 1045228

Showing the first eight; more decompositions exist.
