Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498114, here are decompositions:

3 + 31498111 = 31498114
71 + 31498043 = 31498114
107 + 31498007 = 31498114
173 + 31497941 = 31498114
251 + 31497863 = 31498114
311 + 31497803 = 31498114
317 + 31497797 = 31498114
443 + 31497671 = 31498114

Showing the first eight; more decompositions exist.
