Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461068, here are decompositions:

19 + 31461049 = 31461068
31 + 31461037 = 31461068
61 + 31461007 = 31461068
97 + 31460971 = 31461068
139 + 31460929 = 31461068
151 + 31460917 = 31461068
229 + 31460839 = 31461068
277 + 31460791 = 31461068

Showing the first eight; more decompositions exist.
