Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602506, here are decompositions:

109 + 31602397 = 31602506
139 + 31602367 = 31602506
409 + 31602097 = 31602506
457 + 31602049 = 31602506
643 + 31601863 = 31602506
739 + 31601767 = 31602506
877 + 31601629 = 31602506
937 + 31601569 = 31602506

Showing the first eight; more decompositions exist.
