Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478014, here are decompositions:

23 + 31477991 = 31478014
47 + 31477967 = 31478014
107 + 31477907 = 31478014
131 + 31477883 = 31478014
137 + 31477877 = 31478014
173 + 31477841 = 31478014
233 + 31477781 = 31478014
263 + 31477751 = 31478014

Showing the first eight; more decompositions exist.
