Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589386, here are decompositions:

47 + 31589339 = 31589386
53 + 31589333 = 31589386
83 + 31589303 = 31589386
89 + 31589297 = 31589386
317 + 31589069 = 31589386
359 + 31589027 = 31589386
443 + 31588943 = 31589386
677 + 31588709 = 31589386

Showing the first eight; more decompositions exist.
