Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522564, here are decompositions:

11 + 31522553 = 31522564
23 + 31522541 = 31522564
41 + 31522523 = 31522564
71 + 31522493 = 31522564
113 + 31522451 = 31522564
131 + 31522433 = 31522564
191 + 31522373 = 31522564
233 + 31522331 = 31522564

Showing the first eight; more decompositions exist.
