Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85220, here are decompositions:

7 + 85213 = 85220
19 + 85201 = 85220
61 + 85159 = 85220
73 + 85147 = 85220
127 + 85093 = 85220
139 + 85081 = 85220
193 + 85027 = 85220
199 + 85021 = 85220

Showing the first eight; more decompositions exist.
