Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482644, here are decompositions:

3 + 31482641 = 31482644
13 + 31482631 = 31482644
31 + 31482613 = 31482644
307 + 31482337 = 31482644
337 + 31482307 = 31482644
367 + 31482277 = 31482644
373 + 31482271 = 31482644
397 + 31482247 = 31482644

Showing the first eight; more decompositions exist.
