Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602450, here are decompositions:

7 + 31602443 = 31602450
29 + 31602421 = 31602450
53 + 31602397 = 31602450
83 + 31602367 = 31602450
97 + 31602353 = 31602450
127 + 31602323 = 31602450
199 + 31602251 = 31602450
211 + 31602239 = 31602450

Showing the first eight; more decompositions exist.
