Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601328, here are decompositions:

61 + 31601267 = 31601328
137 + 31601191 = 31601328
149 + 31601179 = 31601328
191 + 31601137 = 31601328
229 + 31601099 = 31601328
251 + 31601077 = 31601328
277 + 31601051 = 31601328
359 + 31600969 = 31601328

Showing the first eight; more decompositions exist.
