Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601310, here are decompositions:

43 + 31601267 = 31601310
47 + 31601263 = 31601310
107 + 31601203 = 31601310
131 + 31601179 = 31601310
173 + 31601137 = 31601310
211 + 31601099 = 31601310
227 + 31601083 = 31601310
233 + 31601077 = 31601310

Showing the first eight; more decompositions exist.
