Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474726, here are decompositions:

5 + 31474721 = 31474726
53 + 31474673 = 31474726
149 + 31474577 = 31474726
167 + 31474559 = 31474726
293 + 31474433 = 31474726
383 + 31474343 = 31474726
419 + 31474307 = 31474726
509 + 31474217 = 31474726

Showing the first eight; more decompositions exist.
