Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8146, here are decompositions:

23 + 8123 = 8146
29 + 8117 = 8146
53 + 8093 = 8146
59 + 8087 = 8146
107 + 8039 = 8146
137 + 8009 = 8146
197 + 7949 = 8146
227 + 7919 = 8146

Showing the first eight; more decompositions exist.
