Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474996, here are decompositions:

167 + 31474829 = 31474996
233 + 31474763 = 31474996
263 + 31474733 = 31474996
419 + 31474577 = 31474996
563 + 31474433 = 31474996
593 + 31474403 = 31474996
599 + 31474397 = 31474996
653 + 31474343 = 31474996

Showing the first eight; more decompositions exist.
