Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532260, here are decompositions:

41 + 31532219 = 31532260
197 + 31532063 = 31532260
239 + 31532021 = 31532260
257 + 31532003 = 31532260
293 + 31531967 = 31532260
443 + 31531817 = 31532260
509 + 31531751 = 31532260
593 + 31531667 = 31532260

Showing the first eight; more decompositions exist.
