Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71000, here are decompositions:

3 + 70997 = 71000
19 + 70981 = 71000
31 + 70969 = 71000
43 + 70957 = 71000
79 + 70921 = 71000
109 + 70891 = 71000
151 + 70849 = 71000
157 + 70843 = 71000

Showing the first eight; more decompositions exist.
