Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482154, here are decompositions:

71 + 31482083 = 31482154
107 + 31482047 = 31482154
113 + 31482041 = 31482154
173 + 31481981 = 31482154
233 + 31481921 = 31482154
311 + 31481843 = 31482154
317 + 31481837 = 31482154
401 + 31481753 = 31482154

Showing the first eight; more decompositions exist.
