Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499016, here are decompositions:

13 + 31499003 = 31499016
23 + 31498993 = 31499016
53 + 31498963 = 31499016
67 + 31498949 = 31499016
103 + 31498913 = 31499016
137 + 31498879 = 31499016
149 + 31498867 = 31499016
163 + 31498853 = 31499016

Showing the first eight; more decompositions exist.
