Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77478, here are decompositions:

7 + 77471 = 77478
31 + 77447 = 77478
47 + 77431 = 77478
59 + 77419 = 77478
61 + 77417 = 77478
101 + 77377 = 77478
109 + 77369 = 77478
127 + 77351 = 77478

Showing the first eight; more decompositions exist.
