Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600850, here are decompositions:

7 + 31600843 = 31600850
67 + 31600783 = 31600850
79 + 31600771 = 31600850
97 + 31600753 = 31600850
109 + 31600741 = 31600850
157 + 31600693 = 31600850
181 + 31600669 = 31600850
397 + 31600453 = 31600850

Showing the first eight; more decompositions exist.
