Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496358, here are decompositions:

29 + 31496329 = 31496358
37 + 31496321 = 31496358
41 + 31496317 = 31496358
97 + 31496261 = 31496358
137 + 31496221 = 31496358
139 + 31496219 = 31496358
149 + 31496209 = 31496358
197 + 31496161 = 31496358

Showing the first eight; more decompositions exist.
