Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459098, here are decompositions:

5 + 31459093 = 31459098
29 + 31459069 = 31459098
67 + 31459031 = 31459098
79 + 31459019 = 31459098
131 + 31458967 = 31459098
191 + 31458907 = 31459098
197 + 31458901 = 31459098
269 + 31458829 = 31459098

Showing the first eight; more decompositions exist.
