Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12888, here are decompositions:

47 + 12841 = 12888
59 + 12829 = 12888
67 + 12821 = 12888
79 + 12809 = 12888
89 + 12799 = 12888
97 + 12791 = 12888
107 + 12781 = 12888
131 + 12757 = 12888

Showing the first eight; more decompositions exist.
