Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514016, here are decompositions:

29 + 31513987 = 31514016
59 + 31513957 = 31514016
73 + 31513943 = 31514016
89 + 31513927 = 31514016
137 + 31513879 = 31514016
139 + 31513877 = 31514016
167 + 31513849 = 31514016
173 + 31513843 = 31514016

Showing the first eight; more decompositions exist.
