Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592466, here are decompositions:

13 + 31592453 = 31592466
19 + 31592447 = 31592466
29 + 31592437 = 31592466
43 + 31592423 = 31592466
89 + 31592377 = 31592466
97 + 31592369 = 31592466
109 + 31592357 = 31592466
263 + 31592203 = 31592466

Showing the first eight; more decompositions exist.
