Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464146, here are decompositions:

3 + 31464143 = 31464146
67 + 31464079 = 31464146
79 + 31464067 = 31464146
349 + 31463797 = 31464146
367 + 31463779 = 31464146
379 + 31463767 = 31464146
433 + 31463713 = 31464146
457 + 31463689 = 31464146

Showing the first eight; more decompositions exist.
