Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489062, here are decompositions:

19 + 31489043 = 31489062
53 + 31489009 = 31489062
71 + 31488991 = 31489062
83 + 31488979 = 31489062
103 + 31488959 = 31489062
131 + 31488931 = 31489062
151 + 31488911 = 31489062
263 + 31488799 = 31489062

Showing the first eight; more decompositions exist.
