Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586088, here are decompositions:

11 + 31586077 = 31586088
29 + 31586059 = 31586088
31 + 31586057 = 31586088
109 + 31585979 = 31586088
151 + 31585937 = 31586088
199 + 31585889 = 31586088
239 + 31585849 = 31586088
251 + 31585837 = 31586088

Showing the first eight; more decompositions exist.
