Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482128, here are decompositions:

31 + 31482097 = 31482128
61 + 31482067 = 31482128
229 + 31481899 = 31482128
241 + 31481887 = 31482128
277 + 31481851 = 31482128
397 + 31481731 = 31482128
607 + 31481521 = 31482128
619 + 31481509 = 31482128

Showing the first eight; more decompositions exist.
