Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532326, here are decompositions:

3 + 31532323 = 31532326
47 + 31532279 = 31532326
107 + 31532219 = 31532326
263 + 31532063 = 31532326
359 + 31531967 = 31532326
443 + 31531883 = 31532326
509 + 31531817 = 31532326
599 + 31531727 = 31532326

Showing the first eight; more decompositions exist.
