Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475376, here are decompositions:

5 + 31475371 = 31475376
59 + 31475317 = 31475376
89 + 31475287 = 31475376
167 + 31475209 = 31475376
269 + 31475107 = 31475376
277 + 31475099 = 31475376
293 + 31475083 = 31475376
307 + 31475069 = 31475376

Showing the first eight; more decompositions exist.
