Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77230, here are decompositions:

17 + 77213 = 77230
29 + 77201 = 77230
59 + 77171 = 77230
89 + 77141 = 77230
137 + 77093 = 77230
149 + 77081 = 77230
227 + 77003 = 77230
239 + 76991 = 77230

Showing the first eight; more decompositions exist.
