Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589086, here are decompositions:

17 + 31589069 = 31589086
29 + 31589057 = 31589086
59 + 31589027 = 31589086
107 + 31588979 = 31589086
239 + 31588847 = 31589086
443 + 31588643 = 31589086
479 + 31588607 = 31589086
563 + 31588523 = 31589086

Showing the first eight; more decompositions exist.
