Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601316, here are decompositions:

53 + 31601263 = 31601316
113 + 31601203 = 31601316
137 + 31601179 = 31601316
179 + 31601137 = 31601316
233 + 31601083 = 31601316
239 + 31601077 = 31601316
293 + 31601023 = 31601316
347 + 31600969 = 31601316

Showing the first eight; more decompositions exist.
