Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7120, here are decompositions:

11 + 7109 = 7120
17 + 7103 = 7120
41 + 7079 = 7120
101 + 7019 = 7120
107 + 7013 = 7120
137 + 6983 = 7120
149 + 6971 = 7120
173 + 6947 = 7120

Showing the first eight; more decompositions exist.
