Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470564, here are decompositions:

7 + 31470557 = 31470564
17 + 31470547 = 31470564
211 + 31470353 = 31470564
227 + 31470337 = 31470564
241 + 31470323 = 31470564
271 + 31470293 = 31470564
347 + 31470217 = 31470564
397 + 31470167 = 31470564

Showing the first eight; more decompositions exist.
