Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4494, here are decompositions:

11 + 4483 = 4494
13 + 4481 = 4494
31 + 4463 = 4494
37 + 4457 = 4494
43 + 4451 = 4494
47 + 4447 = 4494
53 + 4441 = 4494
71 + 4423 = 4494

Showing the first eight; more decompositions exist.
