Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481056, here are decompositions:

17 + 31481039 = 31481056
83 + 31480973 = 31481056
107 + 31480949 = 31481056
137 + 31480919 = 31481056
227 + 31480829 = 31481056
263 + 31480793 = 31481056
293 + 31480763 = 31481056
683 + 31480373 = 31481056

Showing the first eight; more decompositions exist.
