Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18510, here are decompositions:

7 + 18503 = 18510
17 + 18493 = 18510
29 + 18481 = 18510
53 + 18457 = 18510
59 + 18451 = 18510
67 + 18443 = 18510
71 + 18439 = 18510
83 + 18427 = 18510

Showing the first eight; more decompositions exist.
