Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468826, here are decompositions:

3 + 31468823 = 31468826
127 + 31468699 = 31468826
229 + 31468597 = 31468826
283 + 31468543 = 31468826
373 + 31468453 = 31468826
379 + 31468447 = 31468826
457 + 31468369 = 31468826
859 + 31467967 = 31468826

Showing the first eight; more decompositions exist.
