Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447708, here are decompositions:

41 + 31447667 = 31447708
101 + 31447607 = 31447708
179 + 31447529 = 31447708
251 + 31447457 = 31447708
269 + 31447439 = 31447708
491 + 31447217 = 31447708
947 + 31446761 = 31447708
1019 + 31446689 = 31447708

Showing the first eight; more decompositions exist.
