Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72056, here are decompositions:

3 + 72053 = 72056
13 + 72043 = 72056
37 + 72019 = 72056
73 + 71983 = 72056
109 + 71947 = 72056
139 + 71917 = 72056
157 + 71899 = 72056
337 + 71719 = 72056

Showing the first eight; more decompositions exist.
