Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468098, here are decompositions:

31 + 31468067 = 31468098
71 + 31468027 = 31468098
97 + 31468001 = 31468098
131 + 31467967 = 31468098
149 + 31467949 = 31468098
199 + 31467899 = 31468098
251 + 31467847 = 31468098
269 + 31467829 = 31468098

Showing the first eight; more decompositions exist.
