Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567030, here are decompositions:

167 + 31566863 = 31567030
191 + 31566839 = 31567030
227 + 31566803 = 31567030
233 + 31566797 = 31567030
281 + 31566749 = 31567030
293 + 31566737 = 31567030
317 + 31566713 = 31567030
419 + 31566611 = 31567030

Showing the first eight; more decompositions exist.
