Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499104, here are decompositions:

41 + 31499063 = 31499104
47 + 31499057 = 31499104
71 + 31499033 = 31499104
83 + 31499021 = 31499104
101 + 31499003 = 31499104
113 + 31498991 = 31499104
137 + 31498967 = 31499104
173 + 31498931 = 31499104

Showing the first eight; more decompositions exist.
