Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464080, here are decompositions:

13 + 31464067 = 31464080
19 + 31464061 = 31464080
79 + 31464001 = 31464080
139 + 31463941 = 31464080
223 + 31463857 = 31464080
283 + 31463797 = 31464080
313 + 31463767 = 31464080
337 + 31463743 = 31464080

Showing the first eight; more decompositions exist.
