Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496346, here are decompositions:

17 + 31496329 = 31496346
29 + 31496317 = 31496346
53 + 31496293 = 31496346
83 + 31496263 = 31496346
127 + 31496219 = 31496346
137 + 31496209 = 31496346
173 + 31496173 = 31496346
223 + 31496123 = 31496346

Showing the first eight; more decompositions exist.
