Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601340, here are decompositions:

73 + 31601267 = 31601340
137 + 31601203 = 31601340
149 + 31601191 = 31601340
241 + 31601099 = 31601340
257 + 31601083 = 31601340
263 + 31601077 = 31601340
317 + 31601023 = 31601340
347 + 31600993 = 31601340

Showing the first eight; more decompositions exist.
