Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 484, here are decompositions:

5 + 479 = 484
17 + 467 = 484
23 + 461 = 484
41 + 443 = 484
53 + 431 = 484
83 + 401 = 484
101 + 383 = 484
131 + 353 = 484

Showing the first eight; more decompositions exist.
