Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475036, here are decompositions:

7 + 31475029 = 31475036
37 + 31474999 = 31475036
67 + 31474969 = 31475036
163 + 31474873 = 31475036
349 + 31474687 = 31475036
367 + 31474669 = 31475036
487 + 31474549 = 31475036
547 + 31474489 = 31475036

Showing the first eight; more decompositions exist.
