Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498116, here are decompositions:

5 + 31498111 = 31498116
29 + 31498087 = 31498116
47 + 31498069 = 31498116
73 + 31498043 = 31498116
107 + 31498009 = 31498116
109 + 31498007 = 31498116
113 + 31498003 = 31498116
137 + 31497979 = 31498116

Showing the first eight; more decompositions exist.
