Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601752, here are decompositions:

29 + 31601723 = 31601752
41 + 31601711 = 31601752
53 + 31601699 = 31601752
101 + 31601651 = 31601752
239 + 31601513 = 31601752
263 + 31601489 = 31601752
359 + 31601393 = 31601752
653 + 31601099 = 31601752

Showing the first eight; more decompositions exist.
