Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466430, here are decompositions:

29 + 31466401 = 31466430
41 + 31466389 = 31466430
43 + 31466387 = 31466430
89 + 31466341 = 31466430
101 + 31466329 = 31466430
103 + 31466327 = 31466430
139 + 31466291 = 31466430
167 + 31466263 = 31466430

Showing the first eight; more decompositions exist.
