Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469530, here are decompositions:

3 + 31469527 = 31469530
11 + 31469519 = 31469530
17 + 31469513 = 31469530
83 + 31469447 = 31469530
89 + 31469441 = 31469530
107 + 31469423 = 31469530
173 + 31469357 = 31469530
227 + 31469303 = 31469530

Showing the first eight; more decompositions exist.
