Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601306, here are decompositions:

43 + 31601263 = 31601306
103 + 31601203 = 31601306
127 + 31601179 = 31601306
223 + 31601083 = 31601306
229 + 31601077 = 31601306
283 + 31601023 = 31601306
313 + 31600993 = 31601306
337 + 31600969 = 31601306

Showing the first eight; more decompositions exist.
