Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71090, here are decompositions:

31 + 71059 = 71090
67 + 71023 = 71090
79 + 71011 = 71090
109 + 70981 = 71090
139 + 70951 = 71090
199 + 70891 = 71090
211 + 70879 = 71090
223 + 70867 = 71090

Showing the first eight; more decompositions exist.
