Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496480, here are decompositions:

31 + 31496449 = 31496480
61 + 31496419 = 31496480
109 + 31496371 = 31496480
151 + 31496329 = 31496480
163 + 31496317 = 31496480
271 + 31496209 = 31496480
307 + 31496173 = 31496480
397 + 31496083 = 31496480

Showing the first eight; more decompositions exist.
