Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489058, here are decompositions:

31 + 31489027 = 31489058
67 + 31488991 = 31489058
79 + 31488979 = 31489058
127 + 31488931 = 31489058
151 + 31488907 = 31489058
199 + 31488859 = 31489058
439 + 31488619 = 31489058
577 + 31488481 = 31489058

Showing the first eight; more decompositions exist.
