Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482184, here are decompositions:

5 + 31482179 = 31482184
11 + 31482173 = 31482184
17 + 31482167 = 31482184
101 + 31482083 = 31482184
137 + 31482047 = 31482184
233 + 31481951 = 31482184
263 + 31481921 = 31482184
317 + 31481867 = 31482184

Showing the first eight; more decompositions exist.
