Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474194, here are decompositions:

23 + 31474171 = 31474194
53 + 31474141 = 31474194
83 + 31474111 = 31474194
137 + 31474057 = 31474194
151 + 31474043 = 31474194
223 + 31473971 = 31474194
263 + 31473931 = 31474194
277 + 31473917 = 31474194

Showing the first eight; more decompositions exist.
