Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77456, here are decompositions:

37 + 77419 = 77456
73 + 77383 = 77456
79 + 77377 = 77456
97 + 77359 = 77456
109 + 77347 = 77456
139 + 77317 = 77456
193 + 77263 = 77456
409 + 77047 = 77456

Showing the first eight; more decompositions exist.
