Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152020, here are decompositions:

3 + 152017 = 152020
17 + 152003 = 152020
53 + 151967 = 152020
83 + 151937 = 152020
137 + 151883 = 152020
149 + 151871 = 152020
173 + 151847 = 152020
179 + 151841 = 152020

Showing the first eight; more decompositions exist.
