Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542564, here are decompositions:

5 + 31542559 = 31542564
17 + 31542547 = 31542564
41 + 31542523 = 31542564
107 + 31542457 = 31542564
127 + 31542437 = 31542564
167 + 31542397 = 31542564
173 + 31542391 = 31542564
191 + 31542373 = 31542564

Showing the first eight; more decompositions exist.
