Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589976, here are decompositions:

23 + 31589953 = 31589976
53 + 31589923 = 31589976
107 + 31589869 = 31589976
109 + 31589867 = 31589976
149 + 31589827 = 31589976
157 + 31589819 = 31589976
199 + 31589777 = 31589976
239 + 31589737 = 31589976

Showing the first eight; more decompositions exist.
