Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459204, here are decompositions:

3 + 31459201 = 31459204
5 + 31459199 = 31459204
53 + 31459151 = 31459204
71 + 31459133 = 31459204
131 + 31459073 = 31459204
173 + 31459031 = 31459204
251 + 31458953 = 31459204
281 + 31458923 = 31459204

Showing the first eight; more decompositions exist.
