Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78784, here are decompositions:

3 + 78781 = 78784
5 + 78779 = 78784
47 + 78737 = 78784
71 + 78713 = 78784
131 + 78653 = 78784
191 + 78593 = 78784
317 + 78467 = 78784
347 + 78437 = 78784

Showing the first eight; more decompositions exist.
