Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499112, here are decompositions:

5 + 31499107 = 31499112
79 + 31499033 = 31499112
89 + 31499023 = 31499112
109 + 31499003 = 31499112
149 + 31498963 = 31499112
163 + 31498949 = 31499112
181 + 31498931 = 31499112
199 + 31498913 = 31499112

Showing the first eight; more decompositions exist.
