Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602726, here are decompositions:

37 + 31602689 = 31602726
47 + 31602679 = 31602726
53 + 31602673 = 31602726
79 + 31602647 = 31602726
137 + 31602589 = 31602726
139 + 31602587 = 31602726
229 + 31602497 = 31602726
269 + 31602457 = 31602726

Showing the first eight; more decompositions exist.
