Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469446, here are decompositions:

3 + 31469443 = 31469446
5 + 31469441 = 31469446
23 + 31469423 = 31469446
59 + 31469387 = 31469446
89 + 31469357 = 31469446
167 + 31469279 = 31469446
269 + 31469177 = 31469446
419 + 31469027 = 31469446

Showing the first eight; more decompositions exist.
