Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469532, here are decompositions:

5 + 31469527 = 31469532
13 + 31469519 = 31469532
19 + 31469513 = 31469532
89 + 31469443 = 31469532
109 + 31469423 = 31469532
179 + 31469353 = 31469532
229 + 31469303 = 31469532
233 + 31469299 = 31469532

Showing the first eight; more decompositions exist.
