Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7212, here are decompositions:

5 + 7207 = 7212
19 + 7193 = 7212
53 + 7159 = 7212
61 + 7151 = 7212
83 + 7129 = 7212
103 + 7109 = 7212
109 + 7103 = 7212
173 + 7039 = 7212

Showing the first eight; more decompositions exist.
