Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474434, here are decompositions:

11 + 31474423 = 31474434
31 + 31474403 = 31474434
37 + 31474397 = 31474434
71 + 31474363 = 31474434
83 + 31474351 = 31474434
127 + 31474307 = 31474434
181 + 31474253 = 31474434
263 + 31474171 = 31474434

Showing the first eight; more decompositions exist.
