Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150818, here are decompositions:

97 + 150721 = 150818
211 + 150607 = 150818
229 + 150589 = 150818
379 + 150439 = 150818
439 + 150379 = 150818
571 + 150247 = 150818
601 + 150217 = 150818
607 + 150211 = 150818

Showing the first eight; more decompositions exist.
