Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602946, here are decompositions:

29 + 31602917 = 31602946
47 + 31602899 = 31602946
83 + 31602863 = 31602946
257 + 31602689 = 31602946
359 + 31602587 = 31602946
449 + 31602497 = 31602946
503 + 31602443 = 31602946
593 + 31602353 = 31602946

Showing the first eight; more decompositions exist.
