Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575076, here are decompositions:

3 + 31575073 = 31575076
17 + 31575059 = 31575076
107 + 31574969 = 31575076
149 + 31574927 = 31575076
227 + 31574849 = 31575076
263 + 31574813 = 31575076
353 + 31574723 = 31575076
383 + 31574693 = 31575076

Showing the first eight; more decompositions exist.
