Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474756, here are decompositions:

23 + 31474733 = 31474756
83 + 31474673 = 31474756
179 + 31474577 = 31474756
197 + 31474559 = 31474756
353 + 31474403 = 31474756
359 + 31474397 = 31474756
449 + 31474307 = 31474756
503 + 31474253 = 31474756

Showing the first eight; more decompositions exist.
