Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461194, here are decompositions:

3 + 31461191 = 31461194
13 + 31461181 = 31461194
31 + 31461163 = 31461194
67 + 31461127 = 31461194
157 + 31461037 = 31461194
181 + 31461013 = 31461194
223 + 31460971 = 31461194
277 + 31460917 = 31461194

Showing the first eight; more decompositions exist.
