Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498470, here are decompositions:

7 + 31498463 = 31498470
43 + 31498427 = 31498470
103 + 31498367 = 31498470
127 + 31498343 = 31498470
163 + 31498307 = 31498470
181 + 31498289 = 31498470
191 + 31498279 = 31498470
193 + 31498277 = 31498470

Showing the first eight; more decompositions exist.
