Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474204, here are decompositions:

131 + 31474073 = 31474204
197 + 31474007 = 31474204
227 + 31473977 = 31474204
233 + 31473971 = 31474204
317 + 31473887 = 31474204
941 + 31473263 = 31474204
953 + 31473251 = 31474204
1013 + 31473191 = 31474204

Showing the first eight; more decompositions exist.
