Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620484, here are decompositions:

3 + 31620481 = 31620484
11 + 31620473 = 31620484
41 + 31620443 = 31620484
53 + 31620431 = 31620484
167 + 31620317 = 31620484
281 + 31620203 = 31620484
293 + 31620191 = 31620484
317 + 31620167 = 31620484

Showing the first eight; more decompositions exist.
