Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592412, here are decompositions:

23 + 31592389 = 31592412
43 + 31592369 = 31592412
101 + 31592311 = 31592412
193 + 31592219 = 31592412
199 + 31592213 = 31592412
239 + 31592173 = 31592412
251 + 31592161 = 31592412
263 + 31592149 = 31592412

Showing the first eight; more decompositions exist.
