Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601602, here are decompositions:

89 + 31601513 = 31601602
113 + 31601489 = 31601602
191 + 31601411 = 31601602
503 + 31601099 = 31601602
719 + 31600883 = 31601602
743 + 31600859 = 31601602
881 + 31600721 = 31601602
983 + 31600619 = 31601602

Showing the first eight; more decompositions exist.
