Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602078, here are decompositions:

7 + 31602071 = 31602078
29 + 31602049 = 31602078
37 + 31602041 = 31602078
61 + 31602017 = 31602078
181 + 31601897 = 31602078
197 + 31601881 = 31602078
229 + 31601849 = 31602078
241 + 31601837 = 31602078

Showing the first eight; more decompositions exist.
