Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595030, here are decompositions:

31 + 31594999 = 31595030
43 + 31594987 = 31595030
67 + 31594963 = 31595030
127 + 31594903 = 31595030
157 + 31594873 = 31595030
163 + 31594867 = 31595030
223 + 31594807 = 31595030
283 + 31594747 = 31595030

Showing the first eight; more decompositions exist.
