Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602452, here are decompositions:

31 + 31602421 = 31602452
331 + 31602121 = 31602452
373 + 31602079 = 31602452
571 + 31601881 = 31602452
643 + 31601809 = 31602452
709 + 31601743 = 31602452
823 + 31601629 = 31602452
883 + 31601569 = 31602452

Showing the first eight; more decompositions exist.
