Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489896, here are decompositions:

13 + 31489883 = 31489896
17 + 31489879 = 31489896
23 + 31489873 = 31489896
79 + 31489817 = 31489896
149 + 31489747 = 31489896
173 + 31489723 = 31489896
223 + 31489673 = 31489896
233 + 31489663 = 31489896

Showing the first eight; more decompositions exist.
