Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78378, here are decompositions:

11 + 78367 = 78378
31 + 78347 = 78378
37 + 78341 = 78378
61 + 78317 = 78378
67 + 78311 = 78378
71 + 78307 = 78378
101 + 78277 = 78378
137 + 78241 = 78378

Showing the first eight; more decompositions exist.
