Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469098, here are decompositions:

29 + 31469069 = 31469098
71 + 31469027 = 31469098
131 + 31468967 = 31469098
179 + 31468919 = 31469098
197 + 31468901 = 31469098
431 + 31468667 = 31469098
461 + 31468637 = 31469098
467 + 31468631 = 31469098

Showing the first eight; more decompositions exist.
