Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482916, here are decompositions:

83 + 31482833 = 31482916
137 + 31482779 = 31482916
173 + 31482743 = 31482916
233 + 31482683 = 31482916
317 + 31482599 = 31482916
347 + 31482569 = 31482916
659 + 31482257 = 31482916
743 + 31482173 = 31482916

Showing the first eight; more decompositions exist.
