Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602722, here are decompositions:

31 + 31602691 = 31602722
43 + 31602679 = 31602722
61 + 31602661 = 31602722
241 + 31602481 = 31602722
271 + 31602451 = 31602722
601 + 31602121 = 31602722
643 + 31602079 = 31602722
673 + 31602049 = 31602722

Showing the first eight; more decompositions exist.
