Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18072, here are decompositions:

11 + 18061 = 18072
13 + 18059 = 18072
23 + 18049 = 18072
29 + 18043 = 18072
31 + 18041 = 18072
59 + 18013 = 18072
83 + 17989 = 18072
101 + 17971 = 18072

Showing the first eight; more decompositions exist.
