Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602542, here are decompositions:

3 + 31602539 = 31602542
61 + 31602481 = 31602542
379 + 31602163 = 31602542
421 + 31602121 = 31602542
463 + 31602079 = 31602542
619 + 31601923 = 31602542
661 + 31601881 = 31602542
733 + 31601809 = 31602542

Showing the first eight; more decompositions exist.
