Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174, here are decompositions:

7 + 167 = 174
11 + 163 = 174
17 + 157 = 174
23 + 151 = 174
37 + 137 = 174
43 + 131 = 174
47 + 127 = 174
61 + 113 = 174

Showing the first eight; more decompositions exist.
