Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601992, here are decompositions:

5 + 31601987 = 31601992
101 + 31601891 = 31601992
173 + 31601819 = 31601992
269 + 31601723 = 31601992
281 + 31601711 = 31601992
293 + 31601699 = 31601992
479 + 31601513 = 31601992
503 + 31601489 = 31601992

Showing the first eight; more decompositions exist.
