Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541726, here are decompositions:

19 + 31541707 = 31541726
67 + 31541659 = 31541726
157 + 31541569 = 31541726
163 + 31541563 = 31541726
199 + 31541527 = 31541726
277 + 31541449 = 31541726
367 + 31541359 = 31541726
379 + 31541347 = 31541726

Showing the first eight; more decompositions exist.
