Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529162, here are decompositions:

13 + 31529149 = 31529162
73 + 31529089 = 31529162
109 + 31529053 = 31529162
193 + 31528969 = 31529162
331 + 31528831 = 31529162
349 + 31528813 = 31529162
421 + 31528741 = 31529162
433 + 31528729 = 31529162

Showing the first eight; more decompositions exist.
