Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498134, here are decompositions:

11 + 31498123 = 31498134
23 + 31498111 = 31498134
47 + 31498087 = 31498134
127 + 31498007 = 31498134
131 + 31498003 = 31498134
137 + 31497997 = 31498134
193 + 31497941 = 31498134
251 + 31497883 = 31498134

Showing the first eight; more decompositions exist.
