Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469246, here are decompositions:

7 + 31469239 = 31469246
37 + 31469209 = 31469246
103 + 31469143 = 31469246
283 + 31468963 = 31469246
397 + 31468849 = 31469246
547 + 31468699 = 31469246
673 + 31468573 = 31469246
877 + 31468369 = 31469246

Showing the first eight; more decompositions exist.
