Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469536, here are decompositions:

5 + 31469531 = 31469536
17 + 31469519 = 31469536
23 + 31469513 = 31469536
89 + 31469447 = 31469536
113 + 31469423 = 31469536
149 + 31469387 = 31469536
179 + 31469357 = 31469536
233 + 31469303 = 31469536

Showing the first eight; more decompositions exist.
