Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623466, here are decompositions:

5 + 31623461 = 31623466
23 + 31623443 = 31623466
89 + 31623377 = 31623466
257 + 31623209 = 31623466
293 + 31623173 = 31623466
353 + 31623113 = 31623466
419 + 31623047 = 31623466
443 + 31623023 = 31623466

Showing the first eight; more decompositions exist.
