Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152220, here are decompositions:

7 + 152213 = 152220
17 + 152203 = 152220
23 + 152197 = 152220
31 + 152189 = 152220
37 + 152183 = 152220
73 + 152147 = 152220
97 + 152123 = 152220
109 + 152111 = 152220

Showing the first eight; more decompositions exist.
