Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77480, here are decompositions:

3 + 77477 = 77480
61 + 77419 = 77480
97 + 77383 = 77480
103 + 77377 = 77480
157 + 77323 = 77480
163 + 77317 = 77480
211 + 77269 = 77480
241 + 77239 = 77480

Showing the first eight; more decompositions exist.
