Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628094, here are decompositions:

5 + 31628089 = 31628094
73 + 31628021 = 31628094
83 + 31628011 = 31628094
163 + 31627931 = 31628094
167 + 31627927 = 31628094
191 + 31627903 = 31628094
233 + 31627861 = 31628094
283 + 31627811 = 31628094

Showing the first eight; more decompositions exist.
