Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592230, here are decompositions:

11 + 31592219 = 31592230
17 + 31592213 = 31592230
71 + 31592159 = 31592230
101 + 31592129 = 31592230
107 + 31592123 = 31592230
179 + 31592051 = 31592230
191 + 31592039 = 31592230
233 + 31591997 = 31592230

Showing the first eight; more decompositions exist.
