Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475346, here are decompositions:

5 + 31475341 = 31475346
29 + 31475317 = 31475346
59 + 31475287 = 31475346
103 + 31475243 = 31475346
137 + 31475209 = 31475346
157 + 31475189 = 31475346
239 + 31475107 = 31475346
257 + 31475089 = 31475346

Showing the first eight; more decompositions exist.
