Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592292, here are decompositions:

73 + 31592219 = 31592292
79 + 31592213 = 31592292
89 + 31592203 = 31592292
131 + 31592161 = 31592292
163 + 31592129 = 31592292
239 + 31592053 = 31592292
241 + 31592051 = 31592292
293 + 31591999 = 31592292

Showing the first eight; more decompositions exist.
