Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491292, here are decompositions:

13 + 491279 = 491292
19 + 491273 = 491292
31 + 491261 = 491292
41 + 491251 = 491292
73 + 491219 = 491292
79 + 491213 = 491292
163 + 491129 = 491292
211 + 491081 = 491292

Showing the first eight; more decompositions exist.
