Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601270, here are decompositions:

3 + 31601267 = 31601270
7 + 31601263 = 31601270
67 + 31601203 = 31601270
79 + 31601191 = 31601270
193 + 31601077 = 31601270
229 + 31601041 = 31601270
277 + 31600993 = 31601270
313 + 31600957 = 31601270

Showing the first eight; more decompositions exist.
