Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484582, here are decompositions:

13 + 31484569 = 31484582
79 + 31484503 = 31484582
223 + 31484359 = 31484582
229 + 31484353 = 31484582
373 + 31484209 = 31484582
379 + 31484203 = 31484582
421 + 31484161 = 31484582
439 + 31484143 = 31484582

Showing the first eight; more decompositions exist.
