Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470546, here are decompositions:

103 + 31470443 = 31470546
137 + 31470409 = 31470546
167 + 31470379 = 31470546
193 + 31470353 = 31470546
223 + 31470323 = 31470546
337 + 31470209 = 31470546
347 + 31470199 = 31470546
353 + 31470193 = 31470546

Showing the first eight; more decompositions exist.
