Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532252, here are decompositions:

43 + 31532209 = 31532252
139 + 31532113 = 31532252
163 + 31532089 = 31532252
181 + 31532071 = 31532252
331 + 31531921 = 31532252
439 + 31531813 = 31532252
613 + 31531639 = 31532252
673 + 31531579 = 31532252

Showing the first eight; more decompositions exist.
