Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602366, here are decompositions:

13 + 31602353 = 31602366
43 + 31602323 = 31602366
127 + 31602239 = 31602366
139 + 31602227 = 31602366
149 + 31602217 = 31602366
193 + 31602173 = 31602366
223 + 31602143 = 31602366
269 + 31602097 = 31602366

Showing the first eight; more decompositions exist.
