Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469386, here are decompositions:

29 + 31469357 = 31469386
59 + 31469327 = 31469386
83 + 31469303 = 31469386
107 + 31469279 = 31469386
317 + 31469069 = 31469386
353 + 31469033 = 31469386
359 + 31469027 = 31469386
419 + 31468967 = 31469386

Showing the first eight; more decompositions exist.
