Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496398, here are decompositions:

29 + 31496369 = 31496398
137 + 31496261 = 31496398
179 + 31496219 = 31496398
257 + 31496141 = 31496398
419 + 31495979 = 31496398
449 + 31495949 = 31496398
641 + 31495757 = 31496398
797 + 31495601 = 31496398

Showing the first eight; more decompositions exist.
