Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602698, here are decompositions:

7 + 31602691 = 31602698
19 + 31602679 = 31602698
37 + 31602661 = 31602698
67 + 31602631 = 31602698
109 + 31602589 = 31602698
181 + 31602517 = 31602698
241 + 31602457 = 31602698
277 + 31602421 = 31602698

Showing the first eight; more decompositions exist.
