Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588058, here are decompositions:

79 + 31587979 = 31588058
97 + 31587961 = 31588058
109 + 31587949 = 31588058
181 + 31587877 = 31588058
199 + 31587859 = 31588058
241 + 31587817 = 31588058
277 + 31587781 = 31588058
631 + 31587427 = 31588058

Showing the first eight; more decompositions exist.
