Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466458, here are decompositions:

71 + 31466387 = 31466458
131 + 31466327 = 31466458
167 + 31466291 = 31466458
251 + 31466207 = 31466458
479 + 31465979 = 31466458
677 + 31465781 = 31466458
701 + 31465757 = 31466458
761 + 31465697 = 31466458

Showing the first eight; more decompositions exist.
