Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77420, here are decompositions:

3 + 77417 = 77420
37 + 77383 = 77420
43 + 77377 = 77420
61 + 77359 = 77420
73 + 77347 = 77420
97 + 77323 = 77420
103 + 77317 = 77420
151 + 77269 = 77420

Showing the first eight; more decompositions exist.
