Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77272, here are decompositions:

3 + 77269 = 77272
5 + 77267 = 77272
11 + 77261 = 77272
23 + 77249 = 77272
29 + 77243 = 77272
59 + 77213 = 77272
71 + 77201 = 77272
101 + 77171 = 77272

Showing the first eight; more decompositions exist.
