Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464030, here are decompositions:

29 + 31464001 = 31464030
67 + 31463963 = 31464030
71 + 31463959 = 31464030
89 + 31463941 = 31464030
109 + 31463921 = 31464030
137 + 31463893 = 31464030
139 + 31463891 = 31464030
151 + 31463879 = 31464030

Showing the first eight; more decompositions exist.
