Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482564, here are decompositions:

5 + 31482559 = 31482564
13 + 31482551 = 31482564
53 + 31482511 = 31482564
137 + 31482427 = 31482564
163 + 31482401 = 31482564
227 + 31482337 = 31482564
257 + 31482307 = 31482564
271 + 31482293 = 31482564

Showing the first eight; more decompositions exist.
