Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514340, here are decompositions:

31 + 31514309 = 31514340
43 + 31514297 = 31514340
73 + 31514267 = 31514340
79 + 31514261 = 31514340
101 + 31514239 = 31514340
149 + 31514191 = 31514340
181 + 31514159 = 31514340
191 + 31514149 = 31514340

Showing the first eight; more decompositions exist.
