Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534980, here are decompositions:

19 + 31534961 = 31534980
67 + 31534913 = 31534980
101 + 31534879 = 31534980
107 + 31534873 = 31534980
109 + 31534871 = 31534980
149 + 31534831 = 31534980
179 + 31534801 = 31534980
181 + 31534799 = 31534980

Showing the first eight; more decompositions exist.
