Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467876, here are decompositions:

23 + 31467853 = 31467876
29 + 31467847 = 31467876
47 + 31467829 = 31467876
67 + 31467809 = 31467876
109 + 31467767 = 31467876
113 + 31467763 = 31467876
149 + 31467727 = 31467876
157 + 31467719 = 31467876

Showing the first eight; more decompositions exist.
