Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40420, here are decompositions:

59 + 40361 = 40420
131 + 40289 = 40420
137 + 40283 = 40420
167 + 40253 = 40420
179 + 40241 = 40420
227 + 40193 = 40420
251 + 40169 = 40420
257 + 40163 = 40420

Showing the first eight; more decompositions exist.
