Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480016, here are decompositions:

67 + 31479949 = 31480016
199 + 31479817 = 31480016
223 + 31479793 = 31480016
277 + 31479739 = 31480016
367 + 31479649 = 31480016
397 + 31479619 = 31480016
439 + 31479577 = 31480016
457 + 31479559 = 31480016

Showing the first eight; more decompositions exist.
