Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474734, here are decompositions:

13 + 31474721 = 31474734
41 + 31474693 = 31474734
43 + 31474691 = 31474734
47 + 31474687 = 31474734
61 + 31474673 = 31474734
157 + 31474577 = 31474734
163 + 31474571 = 31474734
233 + 31474501 = 31474734

Showing the first eight; more decompositions exist.
