Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609194, here are decompositions:

5 + 31609189 = 31609194
83 + 31609111 = 31609194
101 + 31609093 = 31609194
103 + 31609091 = 31609194
107 + 31609087 = 31609194
163 + 31609031 = 31609194
223 + 31608971 = 31609194
241 + 31608953 = 31609194

Showing the first eight; more decompositions exist.
