Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531754, here are decompositions:

3 + 31531751 = 31531754
127 + 31531627 = 31531754
271 + 31531483 = 31531754
283 + 31531471 = 31531754
337 + 31531417 = 31531754
487 + 31531267 = 31531754
691 + 31531063 = 31531754
811 + 31530943 = 31531754

Showing the first eight; more decompositions exist.
