Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468946, here are decompositions:

43 + 31468903 = 31468946
97 + 31468849 = 31468946
349 + 31468597 = 31468946
373 + 31468573 = 31468946
499 + 31468447 = 31468946
547 + 31468399 = 31468946
577 + 31468369 = 31468946
787 + 31468159 = 31468946

Showing the first eight; more decompositions exist.
