Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77228, here are decompositions:

37 + 77191 = 77228
61 + 77167 = 77228
127 + 77101 = 77228
181 + 77047 = 77228
199 + 77029 = 77228
211 + 77017 = 77228
397 + 76831 = 77228
409 + 76819 = 77228

Showing the first eight; more decompositions exist.
