Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491698, here are decompositions:

29 + 491669 = 491698
47 + 491651 = 491698
59 + 491639 = 491698
71 + 491627 = 491698
107 + 491591 = 491698
167 + 491531 = 491698
197 + 491501 = 491698
269 + 491429 = 491698

Showing the first eight; more decompositions exist.
