Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148100, here are decompositions:

37 + 148063 = 148100
79 + 148021 = 148100
103 + 147997 = 148100
151 + 147949 = 148100
163 + 147937 = 148100
181 + 147919 = 148100
241 + 147859 = 148100
307 + 147793 = 148100

Showing the first eight; more decompositions exist.
