Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602102, here are decompositions:

5 + 31602097 = 31602102
23 + 31602079 = 31602102
31 + 31602071 = 31602102
53 + 31602049 = 31602102
61 + 31602041 = 31602102
179 + 31601923 = 31602102
211 + 31601891 = 31602102
229 + 31601873 = 31602102

Showing the first eight; more decompositions exist.
