Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72048, here are decompositions:

5 + 72043 = 72048
17 + 72031 = 72048
29 + 72019 = 72048
61 + 71987 = 72048
101 + 71947 = 72048
107 + 71941 = 72048
131 + 71917 = 72048
139 + 71909 = 72048

Showing the first eight; more decompositions exist.
