Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71502, here are decompositions:

19 + 71483 = 71502
23 + 71479 = 71502
29 + 71473 = 71502
31 + 71471 = 71502
59 + 71443 = 71502
73 + 71429 = 71502
83 + 71419 = 71502
89 + 71413 = 71502

Showing the first eight; more decompositions exist.
