Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589412, here are decompositions:

5 + 31589407 = 31589412
11 + 31589401 = 31589412
53 + 31589359 = 31589412
59 + 31589353 = 31589412
73 + 31589339 = 31589412
79 + 31589333 = 31589412
83 + 31589329 = 31589412
109 + 31589303 = 31589412

Showing the first eight; more decompositions exist.
