Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575176, here are decompositions:

13 + 31575163 = 31575176
37 + 31575139 = 31575176
103 + 31575073 = 31575176
313 + 31574863 = 31575176
397 + 31574779 = 31575176
487 + 31574689 = 31575176
499 + 31574677 = 31575176
613 + 31574563 = 31575176

Showing the first eight; more decompositions exist.
