Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589424, here are decompositions:

17 + 31589407 = 31589424
23 + 31589401 = 31589424
47 + 31589377 = 31589424
71 + 31589353 = 31589424
103 + 31589321 = 31589424
107 + 31589317 = 31589424
127 + 31589297 = 31589424
131 + 31589293 = 31589424

Showing the first eight; more decompositions exist.
