Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71530, here are decompositions:

3 + 71527 = 71530
47 + 71483 = 71530
59 + 71471 = 71530
101 + 71429 = 71530
131 + 71399 = 71530
167 + 71363 = 71530
191 + 71339 = 71530
197 + 71333 = 71530

Showing the first eight; more decompositions exist.
