Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466500, here are decompositions:

113 + 31466387 = 31466500
173 + 31466327 = 31466500
251 + 31466249 = 31466500
293 + 31466207 = 31466500
449 + 31466051 = 31466500
521 + 31465979 = 31466500
719 + 31465781 = 31466500
743 + 31465757 = 31466500

Showing the first eight; more decompositions exist.
