Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474454, here are decompositions:

31 + 31474423 = 31474454
97 + 31474357 = 31474454
103 + 31474351 = 31474454
163 + 31474291 = 31474454
241 + 31474213 = 31474454
283 + 31474171 = 31474454
313 + 31474141 = 31474454
397 + 31474057 = 31474454

Showing the first eight; more decompositions exist.
