Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76420, here are decompositions:

17 + 76403 = 76420
41 + 76379 = 76420
53 + 76367 = 76420
131 + 76289 = 76420
137 + 76283 = 76420
167 + 76253 = 76420
257 + 76163 = 76420
263 + 76157 = 76420

Showing the first eight; more decompositions exist.
