Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532172, here are decompositions:

5 + 31532167 = 31532172
31 + 31532141 = 31532172
59 + 31532113 = 31532172
83 + 31532089 = 31532172
101 + 31532071 = 31532172
109 + 31532063 = 31532172
151 + 31532021 = 31532172
241 + 31531931 = 31532172

Showing the first eight; more decompositions exist.
