Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576852, here are decompositions:

101 + 31576751 = 31576852
113 + 31576739 = 31576852
149 + 31576703 = 31576852
179 + 31576673 = 31576852
233 + 31576619 = 31576852
269 + 31576583 = 31576852
311 + 31576541 = 31576852
443 + 31576409 = 31576852

Showing the first eight; more decompositions exist.
