Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602126, here are decompositions:

5 + 31602121 = 31602126
29 + 31602097 = 31602126
47 + 31602079 = 31602126
109 + 31602017 = 31602126
139 + 31601987 = 31602126
229 + 31601897 = 31602126
263 + 31601863 = 31602126
277 + 31601849 = 31602126

Showing the first eight; more decompositions exist.
