Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600976, here are decompositions:

7 + 31600969 = 31600976
19 + 31600957 = 31600976
193 + 31600783 = 31600976
223 + 31600753 = 31600976
283 + 31600693 = 31600976
307 + 31600669 = 31600976
313 + 31600663 = 31600976
523 + 31600453 = 31600976

Showing the first eight; more decompositions exist.
