Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464038, here are decompositions:

7 + 31464031 = 31464038
37 + 31464001 = 31464038
79 + 31463959 = 31464038
97 + 31463941 = 31464038
127 + 31463911 = 31464038
181 + 31463857 = 31464038
211 + 31463827 = 31464038
241 + 31463797 = 31464038

Showing the first eight; more decompositions exist.
