Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602458, here are decompositions:

7 + 31602451 = 31602458
37 + 31602421 = 31602458
61 + 31602397 = 31602458
241 + 31602217 = 31602458
337 + 31602121 = 31602458
379 + 31602079 = 31602458
409 + 31602049 = 31602458
577 + 31601881 = 31602458

Showing the first eight; more decompositions exist.
