Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528982, here are decompositions:

13 + 31528969 = 31528982
73 + 31528909 = 31528982
139 + 31528843 = 31528982
151 + 31528831 = 31528982
181 + 31528801 = 31528982
241 + 31528741 = 31528982
313 + 31528669 = 31528982
349 + 31528633 = 31528982

Showing the first eight; more decompositions exist.
