Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469410, here are decompositions:

3 + 31469407 = 31469410
23 + 31469387 = 31469410
53 + 31469357 = 31469410
83 + 31469327 = 31469410
107 + 31469303 = 31469410
131 + 31469279 = 31469410
233 + 31469177 = 31469410
383 + 31469027 = 31469410

Showing the first eight; more decompositions exist.
