Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601836, here are decompositions:

17 + 31601819 = 31601836
53 + 31601783 = 31601836
113 + 31601723 = 31601836
137 + 31601699 = 31601836
269 + 31601567 = 31601836
347 + 31601489 = 31601836
419 + 31601417 = 31601836
443 + 31601393 = 31601836

Showing the first eight; more decompositions exist.
