Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602250, here are decompositions:

11 + 31602239 = 31602250
23 + 31602227 = 31602250
107 + 31602143 = 31602250
179 + 31602071 = 31602250
233 + 31602017 = 31602250
263 + 31601987 = 31602250
353 + 31601897 = 31602250
359 + 31601891 = 31602250

Showing the first eight; more decompositions exist.
