Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464278, here are decompositions:

7 + 31464271 = 31464278
199 + 31464079 = 31464278
211 + 31464067 = 31464278
277 + 31464001 = 31464278
337 + 31463941 = 31464278
367 + 31463911 = 31464278
421 + 31463857 = 31464278
499 + 31463779 = 31464278

Showing the first eight; more decompositions exist.
