Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514006, here are decompositions:

19 + 31513987 = 31514006
79 + 31513927 = 31514006
127 + 31513879 = 31514006
157 + 31513849 = 31514006
163 + 31513843 = 31514006
313 + 31513693 = 31514006
673 + 31513333 = 31514006
787 + 31513219 = 31514006

Showing the first eight; more decompositions exist.
