Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592392, here are decompositions:

3 + 31592389 = 31592392
23 + 31592369 = 31592392
101 + 31592291 = 31592392
173 + 31592219 = 31592392
179 + 31592213 = 31592392
233 + 31592159 = 31592392
263 + 31592129 = 31592392
269 + 31592123 = 31592392

Showing the first eight; more decompositions exist.
