Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461794, here are decompositions:

3 + 31461791 = 31461794
31 + 31461763 = 31461794
97 + 31461697 = 31461794
223 + 31461571 = 31461794
241 + 31461553 = 31461794
271 + 31461523 = 31461794
277 + 31461517 = 31461794
307 + 31461487 = 31461794

Showing the first eight; more decompositions exist.
