Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528022, here are decompositions:

3 + 31528019 = 31528022
109 + 31527913 = 31528022
193 + 31527829 = 31528022
241 + 31527781 = 31528022
313 + 31527709 = 31528022
439 + 31527583 = 31528022
499 + 31527523 = 31528022
523 + 31527499 = 31528022

Showing the first eight; more decompositions exist.
