Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464074, here are decompositions:

7 + 31464067 = 31464074
13 + 31464061 = 31464074
43 + 31464031 = 31464074
73 + 31464001 = 31464074
163 + 31463911 = 31464074
181 + 31463893 = 31464074
277 + 31463797 = 31464074
307 + 31463767 = 31464074

Showing the first eight; more decompositions exist.
