Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534976, here are decompositions:

97 + 31534879 = 31534976
103 + 31534873 = 31534976
157 + 31534819 = 31534976
223 + 31534753 = 31534976
307 + 31534669 = 31534976
379 + 31534597 = 31534976
433 + 31534543 = 31534976
547 + 31534429 = 31534976

Showing the first eight; more decompositions exist.
