Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77288, here are decompositions:

19 + 77269 = 77288
97 + 77191 = 77288
151 + 77137 = 77288
241 + 77047 = 77288
271 + 77017 = 77288
457 + 76831 = 77288
487 + 76801 = 77288
571 + 76717 = 77288

Showing the first eight; more decompositions exist.
