Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474394, here are decompositions:

31 + 31474363 = 31474394
37 + 31474357 = 31474394
43 + 31474351 = 31474394
103 + 31474291 = 31474394
181 + 31474213 = 31474394
223 + 31474171 = 31474394
283 + 31474111 = 31474394
337 + 31474057 = 31474394

Showing the first eight; more decompositions exist.
