Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491496, here are decompositions:

7 + 491489 = 491496
13 + 491483 = 491496
67 + 491429 = 491496
73 + 491423 = 491496
79 + 491417 = 491496
139 + 491357 = 491496
157 + 491339 = 491496
163 + 491333 = 491496

Showing the first eight; more decompositions exist.
