Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531676, here are decompositions:

37 + 31531639 = 31531676
97 + 31531579 = 31531676
193 + 31531483 = 31531676
223 + 31531453 = 31531676
277 + 31531399 = 31531676
307 + 31531369 = 31531676
373 + 31531303 = 31531676
409 + 31531267 = 31531676

Showing the first eight; more decompositions exist.
