Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482006, here are decompositions:

67 + 31481939 = 31482006
107 + 31481899 = 31482006
139 + 31481867 = 31482006
163 + 31481843 = 31482006
239 + 31481767 = 31482006
263 + 31481743 = 31482006
293 + 31481713 = 31482006
383 + 31481623 = 31482006

Showing the first eight; more decompositions exist.
