Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477694, here are decompositions:

37 + 31477657 = 31477694
151 + 31477543 = 31477694
181 + 31477513 = 31477694
211 + 31477483 = 31477694
271 + 31477423 = 31477694
373 + 31477321 = 31477694
487 + 31477207 = 31477694
631 + 31477063 = 31477694

Showing the first eight; more decompositions exist.
