Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532186, here are decompositions:

19 + 31532167 = 31532186
73 + 31532113 = 31532186
97 + 31532089 = 31532186
277 + 31531909 = 31532186
373 + 31531813 = 31532186
547 + 31531639 = 31532186
607 + 31531579 = 31532186
733 + 31531453 = 31532186

Showing the first eight; more decompositions exist.
