Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12784, here are decompositions:

3 + 12781 = 12784
41 + 12743 = 12784
71 + 12713 = 12784
113 + 12671 = 12784
131 + 12653 = 12784
137 + 12647 = 12784
173 + 12611 = 12784
257 + 12527 = 12784

Showing the first eight; more decompositions exist.
