Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77238, here are decompositions:

37 + 77201 = 77238
47 + 77191 = 77238
67 + 77171 = 77238
71 + 77167 = 77238
97 + 77141 = 77238
101 + 77137 = 77238
137 + 77101 = 77238
157 + 77081 = 77238

Showing the first eight; more decompositions exist.
