Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051228, here are decompositions:

47 + 1051181 = 1051228
71 + 1051157 = 1051228
89 + 1051139 = 1051228
149 + 1051079 = 1051228
251 + 1050977 = 1051228
491 + 1050737 = 1051228
617 + 1050611 = 1051228
719 + 1050509 = 1051228

Showing the first eight; more decompositions exist.
