Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506564, here are decompositions:

41 + 31506523 = 31506564
43 + 31506521 = 31506564
53 + 31506511 = 31506564
127 + 31506437 = 31506564
191 + 31506373 = 31506564
197 + 31506367 = 31506564
211 + 31506353 = 31506564
233 + 31506331 = 31506564

Showing the first eight; more decompositions exist.
