Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146220, here are decompositions:

7 + 146213 = 146220
17 + 146203 = 146220
23 + 146197 = 146220
29 + 146191 = 146220
47 + 146173 = 146220
59 + 146161 = 146220
79 + 146141 = 146220
103 + 146117 = 146220

Showing the first eight; more decompositions exist.
