Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109220, here are decompositions:

19 + 109201 = 109220
61 + 109159 = 109220
73 + 109147 = 109220
79 + 109141 = 109220
109 + 109111 = 109220
157 + 109063 = 109220
229 + 108991 = 109220
271 + 108949 = 109220

Showing the first eight; more decompositions exist.
