Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71072, here are decompositions:

3 + 71069 = 71072
13 + 71059 = 71072
61 + 71011 = 71072
73 + 70999 = 71072
103 + 70969 = 71072
151 + 70921 = 71072
181 + 70891 = 71072
193 + 70879 = 71072

Showing the first eight; more decompositions exist.
