Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602672, here are decompositions:

11 + 31602661 = 31602672
41 + 31602631 = 31602672
83 + 31602589 = 31602672
151 + 31602521 = 31602672
191 + 31602481 = 31602672
229 + 31602443 = 31602672
251 + 31602421 = 31602672
271 + 31602401 = 31602672

Showing the first eight; more decompositions exist.
