Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491962, here are decompositions:

11 + 491951 = 491962
89 + 491873 = 491962
173 + 491789 = 491962
179 + 491783 = 491962
293 + 491669 = 491962
311 + 491651 = 491962
431 + 491531 = 491962
461 + 491501 = 491962

Showing the first eight; more decompositions exist.
