Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620096, here are decompositions:

29 + 31620067 = 31620096
37 + 31620059 = 31620096
59 + 31620037 = 31620096
83 + 31620013 = 31620096
103 + 31619993 = 31620096
107 + 31619989 = 31620096
227 + 31619869 = 31620096
307 + 31619789 = 31620096

Showing the first eight; more decompositions exist.
