Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498146, here are decompositions:

23 + 31498123 = 31498146
59 + 31498087 = 31498146
103 + 31498043 = 31498146
107 + 31498039 = 31498146
137 + 31498009 = 31498146
139 + 31498007 = 31498146
149 + 31497997 = 31498146
167 + 31497979 = 31498146

Showing the first eight; more decompositions exist.
