Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469346, here are decompositions:

19 + 31469327 = 31469346
23 + 31469323 = 31469346
43 + 31469303 = 31469346
47 + 31469299 = 31469346
53 + 31469293 = 31469346
59 + 31469287 = 31469346
67 + 31469279 = 31469346
107 + 31469239 = 31469346

Showing the first eight; more decompositions exist.
