Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71002, here are decompositions:

3 + 70999 = 71002
5 + 70997 = 71002
11 + 70991 = 71002
23 + 70979 = 71002
53 + 70949 = 71002
83 + 70919 = 71002
89 + 70913 = 71002
101 + 70901 = 71002

Showing the first eight; more decompositions exist.
