Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460360, here are decompositions:

13 + 31460347 = 31460360
31 + 31460329 = 31460360
67 + 31460293 = 31460360
79 + 31460281 = 31460360
97 + 31460263 = 31460360
163 + 31460197 = 31460360
193 + 31460167 = 31460360
223 + 31460137 = 31460360

Showing the first eight; more decompositions exist.
