Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78468, here are decompositions:

29 + 78439 = 78468
31 + 78437 = 78468
41 + 78427 = 78468
67 + 78401 = 78468
101 + 78367 = 78468
127 + 78341 = 78468
151 + 78317 = 78468
157 + 78311 = 78468

Showing the first eight; more decompositions exist.
