Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529156, here are decompositions:

7 + 31529149 = 31529156
67 + 31529089 = 31529156
103 + 31529053 = 31529156
163 + 31528993 = 31529156
313 + 31528843 = 31529156
349 + 31528807 = 31529156
433 + 31528723 = 31529156
487 + 31528669 = 31529156

Showing the first eight; more decompositions exist.
