Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474924, here are decompositions:

191 + 31474733 = 31474924
233 + 31474691 = 31474924
251 + 31474673 = 31474924
347 + 31474577 = 31474924
353 + 31474571 = 31474924
443 + 31474481 = 31474924
491 + 31474433 = 31474924
521 + 31474403 = 31474924

Showing the first eight; more decompositions exist.
