Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491932, here are decompositions:

59 + 491873 = 491932
113 + 491819 = 491932
149 + 491783 = 491932
263 + 491669 = 491932
281 + 491651 = 491932
293 + 491639 = 491932
401 + 491531 = 491932
431 + 491501 = 491932

Showing the first eight; more decompositions exist.
