Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78718, here are decompositions:

5 + 78713 = 78718
11 + 78707 = 78718
149 + 78569 = 78718
179 + 78539 = 78718
239 + 78479 = 78718
251 + 78467 = 78718
281 + 78437 = 78718
317 + 78401 = 78718

Showing the first eight; more decompositions exist.
