Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475076, here are decompositions:

5 + 31475071 = 31475076
7 + 31475069 = 31475076
23 + 31475053 = 31475076
47 + 31475029 = 31475076
67 + 31475009 = 31475076
79 + 31474997 = 31475076
107 + 31474969 = 31475076
293 + 31474783 = 31475076

Showing the first eight; more decompositions exist.
