Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72026, here are decompositions:

7 + 72019 = 72026
43 + 71983 = 72026
79 + 71947 = 72026
109 + 71917 = 72026
127 + 71899 = 72026
139 + 71887 = 72026
307 + 71719 = 72026
313 + 71713 = 72026

Showing the first eight; more decompositions exist.
