Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466488, here are decompositions:

101 + 31466387 = 31466488
107 + 31466381 = 31466488
197 + 31466291 = 31466488
239 + 31466249 = 31466488
281 + 31466207 = 31466488
509 + 31465979 = 31466488
659 + 31465829 = 31466488
761 + 31465727 = 31466488

Showing the first eight; more decompositions exist.
