Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475334, here are decompositions:

13 + 31475321 = 31475334
17 + 31475317 = 31475334
47 + 31475287 = 31475334
83 + 31475251 = 31475334
103 + 31475231 = 31475334
193 + 31475141 = 31475334
223 + 31475111 = 31475334
227 + 31475107 = 31475334

Showing the first eight; more decompositions exist.
