Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589522, here are decompositions:

61 + 31589461 = 31589522
163 + 31589359 = 31589522
193 + 31589329 = 31589522
229 + 31589293 = 31589522
271 + 31589251 = 31589522
571 + 31588951 = 31589522
709 + 31588813 = 31589522
823 + 31588699 = 31589522

Showing the first eight; more decompositions exist.
