Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592488, here are decompositions:

41 + 31592447 = 31592488
71 + 31592417 = 31592488
131 + 31592357 = 31592488
197 + 31592291 = 31592488
269 + 31592219 = 31592488
359 + 31592129 = 31592488
449 + 31592039 = 31592488
491 + 31591997 = 31592488

Showing the first eight; more decompositions exist.
