Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71510, here are decompositions:

7 + 71503 = 71510
31 + 71479 = 71510
37 + 71473 = 71510
67 + 71443 = 71510
73 + 71437 = 71510
97 + 71413 = 71510
151 + 71359 = 71510
157 + 71353 = 71510

Showing the first eight; more decompositions exist.
