Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592476, here are decompositions:

23 + 31592453 = 31592476
29 + 31592447 = 31592476
53 + 31592423 = 31592476
59 + 31592417 = 31592476
107 + 31592369 = 31592476
257 + 31592219 = 31592476
263 + 31592213 = 31592476
317 + 31592159 = 31592476

Showing the first eight; more decompositions exist.
