Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491692, here are decompositions:

23 + 491669 = 491692
41 + 491651 = 491692
53 + 491639 = 491692
59 + 491633 = 491692
101 + 491591 = 491692
191 + 491501 = 491692
263 + 491429 = 491692
269 + 491423 = 491692

Showing the first eight; more decompositions exist.
