Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592238, here are decompositions:

19 + 31592219 = 31592238
79 + 31592159 = 31592238
89 + 31592149 = 31592238
109 + 31592129 = 31592238
191 + 31592047 = 31592238
199 + 31592039 = 31592238
239 + 31591999 = 31592238
241 + 31591997 = 31592238

Showing the first eight; more decompositions exist.
