Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602372, here are decompositions:

5 + 31602367 = 31602372
19 + 31602353 = 31602372
199 + 31602173 = 31602372
229 + 31602143 = 31602372
251 + 31602121 = 31602372
293 + 31602079 = 31602372
331 + 31602041 = 31602372
449 + 31601923 = 31602372

Showing the first eight; more decompositions exist.
