Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7150, here are decompositions:

23 + 7127 = 7150
29 + 7121 = 7150
41 + 7109 = 7150
47 + 7103 = 7150
71 + 7079 = 7150
107 + 7043 = 7150
131 + 7019 = 7150
137 + 7013 = 7150

Showing the first eight; more decompositions exist.
