Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475674, here are decompositions:

5 + 31475669 = 31475674
281 + 31475393 = 31475674
353 + 31475321 = 31475674
431 + 31475243 = 31475674
443 + 31475231 = 31475674
563 + 31475111 = 31475674
677 + 31474997 = 31475674
743 + 31474931 = 31475674

Showing the first eight; more decompositions exist.
