Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592686, here are decompositions:

3 + 31592683 = 31592686
23 + 31592663 = 31592686
197 + 31592489 = 31592686
233 + 31592453 = 31592686
239 + 31592447 = 31592686
263 + 31592423 = 31592686
269 + 31592417 = 31592686
317 + 31592369 = 31592686

Showing the first eight; more decompositions exist.
