Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475066, here are decompositions:

13 + 31475053 = 31475066
37 + 31475029 = 31475066
67 + 31474999 = 31475066
97 + 31474969 = 31475066
193 + 31474873 = 31475066
199 + 31474867 = 31475066
283 + 31474783 = 31475066
373 + 31474693 = 31475066

Showing the first eight; more decompositions exist.
