Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592530, here are decompositions:

41 + 31592489 = 31592530
83 + 31592447 = 31592530
107 + 31592423 = 31592530
113 + 31592417 = 31592530
173 + 31592357 = 31592530
239 + 31592291 = 31592530
311 + 31592219 = 31592530
317 + 31592213 = 31592530

Showing the first eight; more decompositions exist.
