Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602208, here are decompositions:

137 + 31602071 = 31602208
167 + 31602041 = 31602208
191 + 31602017 = 31602208
311 + 31601897 = 31602208
317 + 31601891 = 31602208
359 + 31601849 = 31602208
389 + 31601819 = 31602208
509 + 31601699 = 31602208

Showing the first eight; more decompositions exist.
