Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620346, here are decompositions:

3 + 31620343 = 31620346
29 + 31620317 = 31620346
47 + 31620299 = 31620346
83 + 31620263 = 31620346
137 + 31620209 = 31620346
179 + 31620167 = 31620346
239 + 31620107 = 31620346
353 + 31619993 = 31620346

Showing the first eight; more decompositions exist.
