Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71512, here are decompositions:

29 + 71483 = 71512
41 + 71471 = 71512
59 + 71453 = 71512
83 + 71429 = 71512
101 + 71411 = 71512
113 + 71399 = 71512
149 + 71363 = 71512
173 + 71339 = 71512

Showing the first eight; more decompositions exist.
