Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469426, here are decompositions:

3 + 31469423 = 31469426
19 + 31469407 = 31469426
73 + 31469353 = 31469426
103 + 31469323 = 31469426
127 + 31469299 = 31469426
139 + 31469287 = 31469426
229 + 31469197 = 31469426
283 + 31469143 = 31469426

Showing the first eight; more decompositions exist.
