Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475262, here are decompositions:

11 + 31475251 = 31475262
19 + 31475243 = 31475262
31 + 31475231 = 31475262
53 + 31475209 = 31475262
73 + 31475189 = 31475262
103 + 31475159 = 31475262
131 + 31475131 = 31475262
151 + 31475111 = 31475262

Showing the first eight; more decompositions exist.
