Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464048, here are decompositions:

17 + 31464031 = 31464048
47 + 31464001 = 31464048
89 + 31463959 = 31464048
107 + 31463941 = 31464048
127 + 31463921 = 31464048
137 + 31463911 = 31464048
139 + 31463909 = 31464048
151 + 31463897 = 31464048

Showing the first eight; more decompositions exist.
