Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546884, here are decompositions:

23 + 31546861 = 31546884
37 + 31546847 = 31546884
41 + 31546843 = 31546884
53 + 31546831 = 31546884
67 + 31546817 = 31546884
71 + 31546813 = 31546884
163 + 31546721 = 31546884
167 + 31546717 = 31546884

Showing the first eight; more decompositions exist.
