Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547052, here are decompositions:

13 + 31547039 = 31547052
71 + 31546981 = 31547052
83 + 31546969 = 31547052
139 + 31546913 = 31547052
191 + 31546861 = 31547052
239 + 31546813 = 31547052
263 + 31546789 = 31547052
293 + 31546759 = 31547052

Showing the first eight; more decompositions exist.
