Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498104, here are decompositions:

17 + 31498087 = 31498104
61 + 31498043 = 31498104
97 + 31498007 = 31498104
101 + 31498003 = 31498104
107 + 31497997 = 31498104
163 + 31497941 = 31498104
173 + 31497931 = 31498104
233 + 31497871 = 31498104

Showing the first eight; more decompositions exist.
