Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623274, here are decompositions:

17 + 31623257 = 31623274
101 + 31623173 = 31623274
107 + 31623167 = 31623274
227 + 31623047 = 31623274
233 + 31623041 = 31623274
251 + 31623023 = 31623274
587 + 31622687 = 31623274
1091 + 31622183 = 31623274

Showing the first eight; more decompositions exist.
