Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532506, here are decompositions:

17 + 31532489 = 31532506
29 + 31532477 = 31532506
167 + 31532339 = 31532506
227 + 31532279 = 31532506
389 + 31532117 = 31532506
443 + 31532063 = 31532506
503 + 31532003 = 31532506
827 + 31531679 = 31532506

Showing the first eight; more decompositions exist.
