Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66378, here are decompositions:

5 + 66373 = 66378
17 + 66361 = 66378
19 + 66359 = 66378
31 + 66347 = 66378
41 + 66337 = 66378
107 + 66271 = 66378
139 + 66239 = 66378
157 + 66221 = 66378

Showing the first eight; more decompositions exist.
