Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600946, here are decompositions:

103 + 31600843 = 31600946
163 + 31600783 = 31600946
193 + 31600753 = 31600946
229 + 31600717 = 31600946
277 + 31600669 = 31600946
283 + 31600663 = 31600946
397 + 31600549 = 31600946
499 + 31600447 = 31600946

Showing the first eight; more decompositions exist.
