Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2896, here are decompositions:

17 + 2879 = 2896
53 + 2843 = 2896
59 + 2837 = 2896
107 + 2789 = 2896
167 + 2729 = 2896
197 + 2699 = 2896
233 + 2663 = 2896
239 + 2657 = 2896

Showing the first eight; more decompositions exist.
