Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576708, here are decompositions:

5 + 31576703 = 31576708
89 + 31576619 = 31576708
167 + 31576541 = 31576708
179 + 31576529 = 31576708
197 + 31576511 = 31576708
269 + 31576439 = 31576708
281 + 31576427 = 31576708
419 + 31576289 = 31576708

Showing the first eight; more decompositions exist.
