Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602028, here are decompositions:

11 + 31602017 = 31602028
41 + 31601987 = 31602028
131 + 31601897 = 31602028
137 + 31601891 = 31602028
179 + 31601849 = 31602028
191 + 31601837 = 31602028
317 + 31601711 = 31602028
461 + 31601567 = 31602028

Showing the first eight; more decompositions exist.
