Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508346, here are decompositions:

17 + 31508329 = 31508346
59 + 31508287 = 31508346
113 + 31508233 = 31508346
167 + 31508179 = 31508346
193 + 31508153 = 31508346
227 + 31508119 = 31508346
239 + 31508107 = 31508346
263 + 31508083 = 31508346

Showing the first eight; more decompositions exist.
