Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533976, here are decompositions:

17 + 31533959 = 31533976
53 + 31533923 = 31533976
137 + 31533839 = 31533976
269 + 31533707 = 31533976
317 + 31533659 = 31533976
389 + 31533587 = 31533976
443 + 31533533 = 31533976
479 + 31533497 = 31533976

Showing the first eight; more decompositions exist.
