Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466520, here are decompositions:

17 + 31466503 = 31466520
131 + 31466389 = 31466520
139 + 31466381 = 31466520
179 + 31466341 = 31466520
191 + 31466329 = 31466520
193 + 31466327 = 31466520
229 + 31466291 = 31466520
233 + 31466287 = 31466520

Showing the first eight; more decompositions exist.
