Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602920, here are decompositions:

3 + 31602917 = 31602920
43 + 31602877 = 31602920
61 + 31602859 = 31602920
67 + 31602853 = 31602920
127 + 31602793 = 31602920
157 + 31602763 = 31602920
229 + 31602691 = 31602920
241 + 31602679 = 31602920

Showing the first eight; more decompositions exist.
