Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147228, here are decompositions:

7 + 147221 = 147228
17 + 147211 = 147228
19 + 147209 = 147228
31 + 147197 = 147228
89 + 147139 = 147228
131 + 147097 = 147228
139 + 147089 = 147228
181 + 147047 = 147228

Showing the first eight; more decompositions exist.
