Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464238, here are decompositions:

5 + 31464233 = 31464238
89 + 31464149 = 31464238
101 + 31464137 = 31464238
191 + 31464047 = 31464238
317 + 31463921 = 31464238
347 + 31463891 = 31464238
359 + 31463879 = 31464238
389 + 31463849 = 31464238

Showing the first eight; more decompositions exist.
