Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620348, here are decompositions:

5 + 31620343 = 31620348
31 + 31620317 = 31620348
47 + 31620301 = 31620348
79 + 31620269 = 31620348
139 + 31620209 = 31620348
157 + 31620191 = 31620348
181 + 31620167 = 31620348
197 + 31620151 = 31620348

Showing the first eight; more decompositions exist.
