Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469692, here are decompositions:

3 + 31469689 = 31469692
71 + 31469621 = 31469692
113 + 31469579 = 31469692
131 + 31469561 = 31469692
173 + 31469519 = 31469692
179 + 31469513 = 31469692
251 + 31469441 = 31469692
269 + 31469423 = 31469692

Showing the first eight; more decompositions exist.
