Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475708, here are decompositions:

31 + 31475677 = 31475708
97 + 31475611 = 31475708
109 + 31475599 = 31475708
127 + 31475581 = 31475708
307 + 31475401 = 31475708
337 + 31475371 = 31475708
367 + 31475341 = 31475708
421 + 31475287 = 31475708

Showing the first eight; more decompositions exist.
