Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467882, here are decompositions:

29 + 31467853 = 31467882
53 + 31467829 = 31467882
71 + 31467811 = 31467882
73 + 31467809 = 31467882
163 + 31467719 = 31467882
191 + 31467691 = 31467882
293 + 31467589 = 31467882
311 + 31467571 = 31467882

Showing the first eight; more decompositions exist.
