Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576726, here are decompositions:

17 + 31576709 = 31576726
23 + 31576703 = 31576726
53 + 31576673 = 31576726
107 + 31576619 = 31576726
197 + 31576529 = 31576726
317 + 31576409 = 31576726
353 + 31576373 = 31576726
359 + 31576367 = 31576726

Showing the first eight; more decompositions exist.
