Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574726, here are decompositions:

3 + 31574723 = 31574726
37 + 31574689 = 31574726
163 + 31574563 = 31574726
229 + 31574497 = 31574726
277 + 31574449 = 31574726
283 + 31574443 = 31574726
307 + 31574419 = 31574726
397 + 31574329 = 31574726

Showing the first eight; more decompositions exist.
