Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474268, here are decompositions:

19 + 31474249 = 31474268
97 + 31474171 = 31474268
127 + 31474141 = 31474268
139 + 31474129 = 31474268
157 + 31474111 = 31474268
211 + 31474057 = 31474268
277 + 31473991 = 31474268
337 + 31473931 = 31474268

Showing the first eight; more decompositions exist.
