Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470134, here are decompositions:

37 + 31470097 = 31470134
61 + 31470073 = 31470134
67 + 31470067 = 31470134
97 + 31470037 = 31470134
181 + 31469953 = 31470134
211 + 31469923 = 31470134
277 + 31469857 = 31470134
337 + 31469797 = 31470134

Showing the first eight; more decompositions exist.
