Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499116, here are decompositions:

53 + 31499063 = 31499116
59 + 31499057 = 31499116
83 + 31499033 = 31499116
113 + 31499003 = 31499116
149 + 31498967 = 31499116
167 + 31498949 = 31499116
263 + 31498853 = 31499116
269 + 31498847 = 31499116

Showing the first eight; more decompositions exist.
