Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464284, here are decompositions:

3 + 31464281 = 31464284
13 + 31464271 = 31464284
97 + 31464187 = 31464284
223 + 31464061 = 31464284
283 + 31464001 = 31464284
373 + 31463911 = 31464284
457 + 31463827 = 31464284
487 + 31463797 = 31464284

Showing the first eight; more decompositions exist.
