Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148146, here are decompositions:

7 + 148139 = 148146
23 + 148123 = 148146
67 + 148079 = 148146
73 + 148073 = 148146
83 + 148063 = 148146
149 + 147997 = 148146
197 + 147949 = 148146
227 + 147919 = 148146

Showing the first eight; more decompositions exist.
