Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468748, here are decompositions:

151 + 31468597 = 31468748
277 + 31468471 = 31468748
349 + 31468399 = 31468748
379 + 31468369 = 31468748
547 + 31468201 = 31468748
601 + 31468147 = 31468748
811 + 31467937 = 31468748
919 + 31467829 = 31468748

Showing the first eight; more decompositions exist.
