Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523644, here are decompositions:

11 + 31523633 = 31523644
107 + 31523537 = 31523644
167 + 31523477 = 31523644
233 + 31523411 = 31523644
263 + 31523381 = 31523644
401 + 31523243 = 31523644
443 + 31523201 = 31523644
563 + 31523081 = 31523644

Showing the first eight; more decompositions exist.
