Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149720, here are decompositions:

3 + 149717 = 149720
7 + 149713 = 149720
31 + 149689 = 149720
97 + 149623 = 149720
157 + 149563 = 149720
199 + 149521 = 149720
223 + 149497 = 149720
229 + 149491 = 149720

Showing the first eight; more decompositions exist.
