Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76320, here are decompositions:

17 + 76303 = 76320
31 + 76289 = 76320
37 + 76283 = 76320
59 + 76261 = 76320
61 + 76259 = 76320
67 + 76253 = 76320
71 + 76249 = 76320
89 + 76231 = 76320

Showing the first eight; more decompositions exist.
