Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71032, here are decompositions:

41 + 70991 = 71032
53 + 70979 = 71032
83 + 70949 = 71032
113 + 70919 = 71032
131 + 70901 = 71032
179 + 70853 = 71032
191 + 70841 = 71032
239 + 70793 = 71032

Showing the first eight; more decompositions exist.
