Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477926, here are decompositions:

19 + 31477907 = 31477926
43 + 31477883 = 31477926
47 + 31477879 = 31477926
127 + 31477799 = 31477926
167 + 31477759 = 31477926
173 + 31477753 = 31477926
197 + 31477729 = 31477926
229 + 31477697 = 31477926

Showing the first eight; more decompositions exist.
