Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7162, here are decompositions:

3 + 7159 = 7162
11 + 7151 = 7162
41 + 7121 = 7162
53 + 7109 = 7162
59 + 7103 = 7162
83 + 7079 = 7162
149 + 7013 = 7162
179 + 6983 = 7162

Showing the first eight; more decompositions exist.
