Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12856, here are decompositions:

3 + 12853 = 12856
47 + 12809 = 12856
113 + 12743 = 12856
167 + 12689 = 12856
197 + 12659 = 12856
317 + 12539 = 12856
353 + 12503 = 12856
359 + 12497 = 12856

Showing the first eight; more decompositions exist.
