Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602100, here are decompositions:

3 + 31602097 = 31602100
29 + 31602071 = 31602100
59 + 31602041 = 31602100
83 + 31602017 = 31602100
113 + 31601987 = 31602100
227 + 31601873 = 31602100
251 + 31601849 = 31602100
263 + 31601837 = 31602100

Showing the first eight; more decompositions exist.
