Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538708, here are decompositions:

37 + 31538671 = 31538708
67 + 31538641 = 31538708
79 + 31538629 = 31538708
127 + 31538581 = 31538708
139 + 31538569 = 31538708
151 + 31538557 = 31538708
181 + 31538527 = 31538708
337 + 31538371 = 31538708

Showing the first eight; more decompositions exist.
