Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468306, here are decompositions:

17 + 31468289 = 31468306
47 + 31468259 = 31468306
59 + 31468247 = 31468306
83 + 31468223 = 31468306
137 + 31468169 = 31468306
239 + 31468067 = 31468306
293 + 31468013 = 31468306
587 + 31467719 = 31468306

Showing the first eight; more decompositions exist.
