Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467866, here are decompositions:

13 + 31467853 = 31467866
19 + 31467847 = 31467866
37 + 31467829 = 31467866
103 + 31467763 = 31467866
139 + 31467727 = 31467866
277 + 31467589 = 31467866
307 + 31467559 = 31467866
433 + 31467433 = 31467866

Showing the first eight; more decompositions exist.
