Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475300, here are decompositions:

13 + 31475287 = 31475300
193 + 31475107 = 31475300
211 + 31475089 = 31475300
229 + 31475071 = 31475300
271 + 31475029 = 31475300
331 + 31474969 = 31475300
433 + 31474867 = 31475300
499 + 31474801 = 31475300

Showing the first eight; more decompositions exist.
