Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531334, here are decompositions:

31 + 31531303 = 31531334
61 + 31531273 = 31531334
67 + 31531267 = 31531334
73 + 31531261 = 31531334
271 + 31531063 = 31531334
277 + 31531057 = 31531334
433 + 31530901 = 31531334
631 + 31530703 = 31531334

Showing the first eight; more decompositions exist.
