Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78320, here are decompositions:

3 + 78317 = 78320
13 + 78307 = 78320
19 + 78301 = 78320
37 + 78283 = 78320
43 + 78277 = 78320
61 + 78259 = 78320
79 + 78241 = 78320
127 + 78193 = 78320

Showing the first eight; more decompositions exist.
