Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471606, here are decompositions:

29 + 31471577 = 31471606
83 + 31471523 = 31471606
137 + 31471469 = 31471606
149 + 31471457 = 31471606
167 + 31471439 = 31471606
233 + 31471373 = 31471606
317 + 31471289 = 31471606
389 + 31471217 = 31471606

Showing the first eight; more decompositions exist.
