Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534726, here are decompositions:

17 + 31534709 = 31534726
89 + 31534637 = 31534726
137 + 31534589 = 31534726
173 + 31534553 = 31534726
233 + 31534493 = 31534726
239 + 31534487 = 31534726
269 + 31534457 = 31534726
383 + 31534343 = 31534726

Showing the first eight; more decompositions exist.
