Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496252, here are decompositions:

31 + 31496221 = 31496252
43 + 31496209 = 31496252
79 + 31496173 = 31496252
211 + 31496041 = 31496252
241 + 31496011 = 31496252
331 + 31495921 = 31496252
373 + 31495879 = 31496252
433 + 31495819 = 31496252

Showing the first eight; more decompositions exist.
