Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602180, here are decompositions:

7 + 31602173 = 31602180
17 + 31602163 = 31602180
37 + 31602143 = 31602180
59 + 31602121 = 31602180
83 + 31602097 = 31602180
101 + 31602079 = 31602180
109 + 31602071 = 31602180
131 + 31602049 = 31602180

Showing the first eight; more decompositions exist.
