Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602602, here are decompositions:

13 + 31602589 = 31602602
151 + 31602451 = 31602602
181 + 31602421 = 31602602
439 + 31602163 = 31602602
523 + 31602079 = 31602602
739 + 31601863 = 31602602
859 + 31601743 = 31602602
1033 + 31601569 = 31602602

Showing the first eight; more decompositions exist.
