Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459298, here are decompositions:

7 + 31459291 = 31459298
37 + 31459261 = 31459298
97 + 31459201 = 31459298
229 + 31459069 = 31459298
331 + 31458967 = 31459298
397 + 31458901 = 31459298
499 + 31458799 = 31459298
601 + 31458697 = 31459298

Showing the first eight; more decompositions exist.
