Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491562, here are decompositions:

23 + 491539 = 491562
31 + 491531 = 491562
59 + 491503 = 491562
61 + 491501 = 491562
73 + 491489 = 491562
79 + 491483 = 491562
101 + 491461 = 491562
139 + 491423 = 491562

Showing the first eight; more decompositions exist.
