Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71506, here are decompositions:

3 + 71503 = 71506
23 + 71483 = 71506
53 + 71453 = 71506
107 + 71399 = 71506
167 + 71339 = 71506
173 + 71333 = 71506
179 + 71327 = 71506
257 + 71249 = 71506

Showing the first eight; more decompositions exist.
