Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592250, here are decompositions:

31 + 31592219 = 31592250
37 + 31592213 = 31592250
47 + 31592203 = 31592250
89 + 31592161 = 31592250
101 + 31592149 = 31592250
127 + 31592123 = 31592250
197 + 31592053 = 31592250
199 + 31592051 = 31592250

Showing the first eight; more decompositions exist.
