Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592482, here are decompositions:

29 + 31592453 = 31592482
59 + 31592423 = 31592482
71 + 31592411 = 31592482
113 + 31592369 = 31592482
191 + 31592291 = 31592482
263 + 31592219 = 31592482
269 + 31592213 = 31592482
353 + 31592129 = 31592482

Showing the first eight; more decompositions exist.
