Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477976, here are decompositions:

7 + 31477969 = 31477976
97 + 31477879 = 31477976
223 + 31477753 = 31477976
307 + 31477669 = 31477976
373 + 31477603 = 31477976
433 + 31477543 = 31477976
463 + 31477513 = 31477976
547 + 31477429 = 31477976

Showing the first eight; more decompositions exist.
