Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496432, here are decompositions:

3 + 31496429 = 31496432
13 + 31496419 = 31496432
43 + 31496389 = 31496432
61 + 31496371 = 31496432
103 + 31496329 = 31496432
139 + 31496293 = 31496432
211 + 31496221 = 31496432
223 + 31496209 = 31496432

Showing the first eight; more decompositions exist.
