Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140426, here are decompositions:

3 + 140423 = 140426
7 + 140419 = 140426
19 + 140407 = 140426
109 + 140317 = 140426
157 + 140269 = 140426
163 + 140263 = 140426
199 + 140227 = 140426
229 + 140197 = 140426

Showing the first eight; more decompositions exist.
