Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497410, here are decompositions:

19 + 31497391 = 31497410
73 + 31497337 = 31497410
97 + 31497313 = 31497410
127 + 31497283 = 31497410
181 + 31497229 = 31497410
223 + 31497187 = 31497410
271 + 31497139 = 31497410
277 + 31497133 = 31497410

Showing the first eight; more decompositions exist.
