Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532430, here are decompositions:

29 + 31532401 = 31532430
89 + 31532341 = 31532430
101 + 31532329 = 31532430
107 + 31532323 = 31532430
151 + 31532279 = 31532430
211 + 31532219 = 31532430
227 + 31532203 = 31532430
263 + 31532167 = 31532430

Showing the first eight; more decompositions exist.
