Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482482, here are decompositions:

43 + 31482439 = 31482482
139 + 31482343 = 31482482
211 + 31482271 = 31482482
313 + 31482169 = 31482482
379 + 31482103 = 31482482
439 + 31482043 = 31482482
571 + 31481911 = 31482482
631 + 31481851 = 31482482

Showing the first eight; more decompositions exist.
