Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494, here are decompositions:

3 + 491 = 494
7 + 487 = 494
31 + 463 = 494
37 + 457 = 494
61 + 433 = 494
73 + 421 = 494
97 + 397 = 494
127 + 367 = 494

Showing the first eight; more decompositions exist.
