Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529446, here are decompositions:

167 + 31529279 = 31529446
173 + 31529273 = 31529446
197 + 31529249 = 31529446
227 + 31529219 = 31529446
233 + 31529213 = 31529446
359 + 31529087 = 31529446
449 + 31528997 = 31529446
479 + 31528967 = 31529446

Showing the first eight; more decompositions exist.
