Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589358, here are decompositions:

5 + 31589353 = 31589358
19 + 31589339 = 31589358
29 + 31589329 = 31589358
37 + 31589321 = 31589358
41 + 31589317 = 31589358
61 + 31589297 = 31589358
67 + 31589291 = 31589358
71 + 31589287 = 31589358

Showing the first eight; more decompositions exist.
