Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493174, here are decompositions:

3 + 31493171 = 31493174
43 + 31493131 = 31493174
127 + 31493047 = 31493174
157 + 31493017 = 31493174
211 + 31492963 = 31493174
241 + 31492933 = 31493174
337 + 31492837 = 31493174
373 + 31492801 = 31493174

Showing the first eight; more decompositions exist.
