Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623350, here are decompositions:

7 + 31623343 = 31623350
13 + 31623337 = 31623350
127 + 31623223 = 31623350
139 + 31623211 = 31623350
151 + 31623199 = 31623350
181 + 31623169 = 31623350
229 + 31623121 = 31623350
457 + 31622893 = 31623350

Showing the first eight; more decompositions exist.
