Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497326, here are decompositions:

13 + 31497313 = 31497326
43 + 31497283 = 31497326
97 + 31497229 = 31497326
103 + 31497223 = 31497326
139 + 31497187 = 31497326
193 + 31497133 = 31497326
199 + 31497127 = 31497326
337 + 31496989 = 31497326

Showing the first eight; more decompositions exist.
