Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475108, here are decompositions:

19 + 31475089 = 31475108
37 + 31475071 = 31475108
79 + 31475029 = 31475108
109 + 31474999 = 31475108
127 + 31474981 = 31475108
139 + 31474969 = 31475108
241 + 31474867 = 31475108
307 + 31474801 = 31475108

Showing the first eight; more decompositions exist.
