Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77146, here are decompositions:

5 + 77141 = 77146
53 + 77093 = 77146
197 + 76949 = 77146
227 + 76919 = 77146
233 + 76913 = 77146
239 + 76907 = 77146
263 + 76883 = 77146
317 + 76829 = 77146

Showing the first eight; more decompositions exist.
