Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532306, here are decompositions:

37 + 31532269 = 31532306
79 + 31532227 = 31532306
97 + 31532209 = 31532306
103 + 31532203 = 31532306
139 + 31532167 = 31532306
193 + 31532113 = 31532306
397 + 31531909 = 31532306
727 + 31531579 = 31532306

Showing the first eight; more decompositions exist.
