Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620332, here are decompositions:

31 + 31620301 = 31620332
103 + 31620229 = 31620332
109 + 31620223 = 31620332
181 + 31620151 = 31620332
193 + 31620139 = 31620332
223 + 31620109 = 31620332
313 + 31620019 = 31620332
379 + 31619953 = 31620332

Showing the first eight; more decompositions exist.
