Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602472, here are decompositions:

29 + 31602443 = 31602472
71 + 31602401 = 31602472
149 + 31602323 = 31602472
191 + 31602281 = 31602472
233 + 31602239 = 31602472
401 + 31602071 = 31602472
431 + 31602041 = 31602472
599 + 31601873 = 31602472

Showing the first eight; more decompositions exist.
