Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518546, here are decompositions:

5 + 31518541 = 31518546
23 + 31518523 = 31518546
79 + 31518467 = 31518546
89 + 31518457 = 31518546
167 + 31518379 = 31518546
193 + 31518353 = 31518546
233 + 31518313 = 31518546
307 + 31518239 = 31518546

Showing the first eight; more decompositions exist.
