Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496392, here are decompositions:

3 + 31496389 = 31496392
23 + 31496369 = 31496392
71 + 31496321 = 31496392
131 + 31496261 = 31496392
173 + 31496219 = 31496392
251 + 31496141 = 31496392
269 + 31496123 = 31496392
293 + 31496099 = 31496392

Showing the first eight; more decompositions exist.
