Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475852, here are decompositions:

3 + 31475849 = 31475852
73 + 31475779 = 31475852
103 + 31475749 = 31475852
139 + 31475713 = 31475852
229 + 31475623 = 31475852
241 + 31475611 = 31475852
271 + 31475581 = 31475852
409 + 31475443 = 31475852

Showing the first eight; more decompositions exist.
