Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7190, here are decompositions:

3 + 7187 = 7190
13 + 7177 = 7190
31 + 7159 = 7190
61 + 7129 = 7190
151 + 7039 = 7190
163 + 7027 = 7190
193 + 6997 = 7190
199 + 6991 = 7190

Showing the first eight; more decompositions exist.
