Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592346, here are decompositions:

89 + 31592257 = 31592346
127 + 31592219 = 31592346
173 + 31592173 = 31592346
197 + 31592149 = 31592346
223 + 31592123 = 31592346
293 + 31592053 = 31592346
307 + 31592039 = 31592346
347 + 31591999 = 31592346

Showing the first eight; more decompositions exist.
