Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468982, here are decompositions:

19 + 31468963 = 31468982
79 + 31468903 = 31468982
283 + 31468699 = 31468982
409 + 31468573 = 31468982
439 + 31468543 = 31468982
613 + 31468369 = 31468982
739 + 31468243 = 31468982
751 + 31468231 = 31468982

Showing the first eight; more decompositions exist.
