Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469466, here are decompositions:

19 + 31469447 = 31469466
23 + 31469443 = 31469466
43 + 31469423 = 31469466
59 + 31469407 = 31469466
79 + 31469387 = 31469466
109 + 31469357 = 31469466
113 + 31469353 = 31469466
139 + 31469327 = 31469466

Showing the first eight; more decompositions exist.
