Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12718, here are decompositions:

5 + 12713 = 12718
29 + 12689 = 12718
47 + 12671 = 12718
59 + 12659 = 12718
71 + 12647 = 12718
107 + 12611 = 12718
149 + 12569 = 12718
179 + 12539 = 12718

Showing the first eight; more decompositions exist.
