Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471702, here are decompositions:

5 + 31471697 = 31471702
179 + 31471523 = 31471702
191 + 31471511 = 31471702
233 + 31471469 = 31471702
263 + 31471439 = 31471702
593 + 31471109 = 31471702
659 + 31471043 = 31471702
701 + 31471001 = 31471702

Showing the first eight; more decompositions exist.
