Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494174, here are decompositions:

13 + 31494161 = 31494174
17 + 31494157 = 31494174
31 + 31494143 = 31494174
83 + 31494091 = 31494174
191 + 31493983 = 31494174
223 + 31493951 = 31494174
233 + 31493941 = 31494174
293 + 31493881 = 31494174

Showing the first eight; more decompositions exist.
