Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571726, here are decompositions:

19 + 31571707 = 31571726
73 + 31571653 = 31571726
79 + 31571647 = 31571726
157 + 31571569 = 31571726
229 + 31571497 = 31571726
313 + 31571413 = 31571726
337 + 31571389 = 31571726
379 + 31571347 = 31571726

Showing the first eight; more decompositions exist.
