Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602434, here are decompositions:

13 + 31602421 = 31602434
37 + 31602397 = 31602434
67 + 31602367 = 31602434
271 + 31602163 = 31602434
313 + 31602121 = 31602434
337 + 31602097 = 31602434
571 + 31601863 = 31602434
691 + 31601743 = 31602434

Showing the first eight; more decompositions exist.
