Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601936, here are decompositions:

13 + 31601923 = 31601936
73 + 31601863 = 31601936
127 + 31601809 = 31601936
193 + 31601743 = 31601936
229 + 31601707 = 31601936
307 + 31601629 = 31601936
367 + 31601569 = 31601936
397 + 31601539 = 31601936

Showing the first eight; more decompositions exist.
