Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602162, here are decompositions:

19 + 31602143 = 31602162
41 + 31602121 = 31602162
83 + 31602079 = 31602162
113 + 31602049 = 31602162
239 + 31601923 = 31602162
271 + 31601891 = 31602162
281 + 31601881 = 31602162
313 + 31601849 = 31602162

Showing the first eight; more decompositions exist.
