Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532368, here are decompositions:

29 + 31532339 = 31532368
89 + 31532279 = 31532368
107 + 31532261 = 31532368
149 + 31532219 = 31532368
227 + 31532141 = 31532368
251 + 31532117 = 31532368
347 + 31532021 = 31532368
401 + 31531967 = 31532368

Showing the first eight; more decompositions exist.
