Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491944, here are decompositions:

71 + 491873 = 491944
107 + 491837 = 491944
197 + 491747 = 491944
293 + 491651 = 491944
311 + 491633 = 491944
317 + 491627 = 491944
353 + 491591 = 491944
443 + 491501 = 491944

Showing the first eight; more decompositions exist.
