Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604224, here are decompositions:

5 + 31604219 = 31604224
167 + 31604057 = 31604224
173 + 31604051 = 31604224
191 + 31604033 = 31604224
233 + 31603991 = 31604224
293 + 31603931 = 31604224
347 + 31603877 = 31604224
467 + 31603757 = 31604224

Showing the first eight; more decompositions exist.
