Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109420, here are decompositions:

23 + 109397 = 109420
29 + 109391 = 109420
41 + 109379 = 109420
53 + 109367 = 109420
89 + 109331 = 109420
107 + 109313 = 109420
167 + 109253 = 109420
191 + 109229 = 109420

Showing the first eight; more decompositions exist.
