Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602210, here are decompositions:

37 + 31602173 = 31602210
47 + 31602163 = 31602210
67 + 31602143 = 31602210
89 + 31602121 = 31602210
113 + 31602097 = 31602210
131 + 31602079 = 31602210
139 + 31602071 = 31602210
193 + 31602017 = 31602210

Showing the first eight; more decompositions exist.
