Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547332, here are decompositions:

29 + 31547303 = 31547332
71 + 31547261 = 31547332
101 + 31547231 = 31547332
239 + 31547093 = 31547332
269 + 31547063 = 31547332
293 + 31547039 = 31547332
419 + 31546913 = 31547332
863 + 31546469 = 31547332

Showing the first eight; more decompositions exist.
