Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620196, here are decompositions:

5 + 31620191 = 31620196
29 + 31620167 = 31620196
89 + 31620107 = 31620196
137 + 31620059 = 31620196
347 + 31619849 = 31620196
353 + 31619843 = 31620196
389 + 31619807 = 31620196
479 + 31619717 = 31620196

Showing the first eight; more decompositions exist.
