Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152228, here are decompositions:

31 + 152197 = 152228
151 + 152077 = 152228
199 + 152029 = 152228
211 + 152017 = 152228
331 + 151897 = 152228
379 + 151849 = 152228
457 + 151771 = 152228
499 + 151729 = 152228

Showing the first eight; more decompositions exist.
