Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71526, here are decompositions:

23 + 71503 = 71526
43 + 71483 = 71526
47 + 71479 = 71526
53 + 71473 = 71526
73 + 71453 = 71526
83 + 71443 = 71526
89 + 71437 = 71526
97 + 71429 = 71526

Showing the first eight; more decompositions exist.
