Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187190, here are decompositions:

13 + 187177 = 187190
19 + 187171 = 187190
61 + 187129 = 187190
67 + 187123 = 187190
79 + 187111 = 187190
109 + 187081 = 187190
163 + 187027 = 187190
181 + 187009 = 187190

Showing the first eight; more decompositions exist.
