Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77488, here are decompositions:

11 + 77477 = 77488
17 + 77471 = 77488
41 + 77447 = 77488
71 + 77417 = 77488
137 + 77351 = 77488
149 + 77339 = 77488
197 + 77291 = 77488
227 + 77261 = 77488

Showing the first eight; more decompositions exist.
