Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467474, here are decompositions:

7 + 31467467 = 31467474
37 + 31467437 = 31467474
41 + 31467433 = 31467474
43 + 31467431 = 31467474
107 + 31467367 = 31467474
127 + 31467347 = 31467474
163 + 31467311 = 31467474
173 + 31467301 = 31467474

Showing the first eight; more decompositions exist.
