Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7156, here are decompositions:

5 + 7151 = 7156
29 + 7127 = 7156
47 + 7109 = 7156
53 + 7103 = 7156
113 + 7043 = 7156
137 + 7019 = 7156
173 + 6983 = 7156
179 + 6977 = 7156

Showing the first eight; more decompositions exist.
