Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18462, here are decompositions:

5 + 18457 = 18462
11 + 18451 = 18462
19 + 18443 = 18462
23 + 18439 = 18462
29 + 18433 = 18462
61 + 18401 = 18462
83 + 18379 = 18462
109 + 18353 = 18462

Showing the first eight; more decompositions exist.
