Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488466, here are decompositions:

3 + 31488463 = 31488466
59 + 31488407 = 31488466
137 + 31488329 = 31488466
167 + 31488299 = 31488466
173 + 31488293 = 31488466
239 + 31488227 = 31488466
263 + 31488203 = 31488466
509 + 31487957 = 31488466

Showing the first eight; more decompositions exist.
