Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474310, here are decompositions:

3 + 31474307 = 31474310
19 + 31474291 = 31474310
61 + 31474249 = 31474310
97 + 31474213 = 31474310
139 + 31474171 = 31474310
181 + 31474129 = 31474310
199 + 31474111 = 31474310
277 + 31474033 = 31474310

Showing the first eight; more decompositions exist.
