Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620234, here are decompositions:

5 + 31620229 = 31620234
11 + 31620223 = 31620234
31 + 31620203 = 31620234
43 + 31620191 = 31620234
67 + 31620167 = 31620234
83 + 31620151 = 31620234
103 + 31620131 = 31620234
127 + 31620107 = 31620234

Showing the first eight; more decompositions exist.
