Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945228, here are decompositions:

17 + 945211 = 945228
19 + 945209 = 945228
139 + 945089 = 945228
191 + 945037 = 945228
197 + 945031 = 945228
241 + 944987 = 945228
331 + 944897 = 945228
499 + 944729 = 945228

Showing the first eight; more decompositions exist.
