Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623246, here are decompositions:

23 + 31623223 = 31623246
37 + 31623209 = 31623246
47 + 31623199 = 31623246
73 + 31623173 = 31623246
79 + 31623167 = 31623246
199 + 31623047 = 31623246
223 + 31623023 = 31623246
307 + 31622939 = 31623246

Showing the first eight; more decompositions exist.
