Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471698, here are decompositions:

17 + 31471681 = 31471698
31 + 31471667 = 31471698
59 + 31471639 = 31471698
61 + 31471637 = 31471698
107 + 31471591 = 31471698
149 + 31471549 = 31471698
229 + 31471469 = 31471698
241 + 31471457 = 31471698

Showing the first eight; more decompositions exist.
