Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475214, here are decompositions:

5 + 31475209 = 31475214
73 + 31475141 = 31475214
83 + 31475131 = 31475214
103 + 31475111 = 31475214
107 + 31475107 = 31475214
131 + 31475083 = 31475214
233 + 31474981 = 31475214
283 + 31474931 = 31475214

Showing the first eight; more decompositions exist.
