Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589456, here are decompositions:

79 + 31589377 = 31589456
97 + 31589359 = 31589456
103 + 31589353 = 31589456
127 + 31589329 = 31589456
139 + 31589317 = 31589456
163 + 31589293 = 31589456
337 + 31589119 = 31589456
439 + 31589017 = 31589456

Showing the first eight; more decompositions exist.
