Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536182, here are decompositions:

163 + 31536019 = 31536182
199 + 31535983 = 31536182
241 + 31535941 = 31536182
373 + 31535809 = 31536182
631 + 31535551 = 31536182
919 + 31535263 = 31536182
1009 + 31535173 = 31536182
1039 + 31535143 = 31536182

Showing the first eight; more decompositions exist.
