Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602318, here are decompositions:

37 + 31602281 = 31602318
67 + 31602251 = 31602318
79 + 31602239 = 31602318
101 + 31602217 = 31602318
197 + 31602121 = 31602318
239 + 31602079 = 31602318
269 + 31602049 = 31602318
277 + 31602041 = 31602318

Showing the first eight; more decompositions exist.
