Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469412, here are decompositions:

5 + 31469407 = 31469412
59 + 31469353 = 31469412
89 + 31469323 = 31469412
109 + 31469303 = 31469412
113 + 31469299 = 31469412
173 + 31469239 = 31469412
269 + 31469143 = 31469412
281 + 31469131 = 31469412

Showing the first eight; more decompositions exist.
