Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71078, here are decompositions:

19 + 71059 = 71078
67 + 71011 = 71078
79 + 70999 = 71078
97 + 70981 = 71078
109 + 70969 = 71078
127 + 70951 = 71078
157 + 70921 = 71078
199 + 70879 = 71078

Showing the first eight; more decompositions exist.
