Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71516, here are decompositions:

13 + 71503 = 71516
37 + 71479 = 71516
43 + 71473 = 71516
73 + 71443 = 71516
79 + 71437 = 71516
97 + 71419 = 71516
103 + 71413 = 71516
127 + 71389 = 71516

Showing the first eight; more decompositions exist.
