Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496582, here are decompositions:

31 + 31496551 = 31496582
43 + 31496539 = 31496582
163 + 31496419 = 31496582
193 + 31496389 = 31496582
211 + 31496371 = 31496582
373 + 31496209 = 31496582
409 + 31496173 = 31496582
421 + 31496161 = 31496582

Showing the first eight; more decompositions exist.
