Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468948, here are decompositions:

29 + 31468919 = 31468948
47 + 31468901 = 31468948
191 + 31468757 = 31468948
281 + 31468667 = 31468948
311 + 31468637 = 31468948
317 + 31468631 = 31468948
359 + 31468589 = 31468948
389 + 31468559 = 31468948

Showing the first eight; more decompositions exist.
