Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500, here are decompositions:

13 + 487 = 500
37 + 463 = 500
43 + 457 = 500
61 + 439 = 500
67 + 433 = 500
79 + 421 = 500
103 + 397 = 500
127 + 373 = 500

Showing the first eight; more decompositions exist.
