Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602138, here are decompositions:

17 + 31602121 = 31602138
41 + 31602097 = 31602138
59 + 31602079 = 31602138
67 + 31602071 = 31602138
89 + 31602049 = 31602138
97 + 31602041 = 31602138
151 + 31601987 = 31602138
241 + 31601897 = 31602138

Showing the first eight; more decompositions exist.
