Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78462, here are decompositions:

23 + 78439 = 78462
61 + 78401 = 78462
151 + 78311 = 78462
179 + 78283 = 78462
229 + 78233 = 78462
233 + 78229 = 78462
269 + 78193 = 78462
271 + 78191 = 78462

Showing the first eight; more decompositions exist.
