Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5156, here are decompositions:

3 + 5153 = 5156
37 + 5119 = 5156
43 + 5113 = 5156
79 + 5077 = 5156
97 + 5059 = 5156
157 + 4999 = 5156
163 + 4993 = 5156
199 + 4957 = 5156

Showing the first eight; more decompositions exist.
