Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71030, here are decompositions:

7 + 71023 = 71030
19 + 71011 = 71030
31 + 70999 = 71030
61 + 70969 = 71030
73 + 70957 = 71030
79 + 70951 = 71030
109 + 70921 = 71030
139 + 70891 = 71030

Showing the first eight; more decompositions exist.
