Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463504, here are decompositions:

97 + 31463407 = 31463504
151 + 31463353 = 31463504
223 + 31463281 = 31463504
277 + 31463227 = 31463504
307 + 31463197 = 31463504
337 + 31463167 = 31463504
367 + 31463137 = 31463504
421 + 31463083 = 31463504

Showing the first eight; more decompositions exist.
