Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468930, here are decompositions:

11 + 31468919 = 31468930
29 + 31468901 = 31468930
107 + 31468823 = 31468930
137 + 31468793 = 31468930
173 + 31468757 = 31468930
263 + 31468667 = 31468930
293 + 31468637 = 31468930
359 + 31468571 = 31468930

Showing the first eight; more decompositions exist.
