Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71524, here are decompositions:

41 + 71483 = 71524
53 + 71471 = 71524
71 + 71453 = 71524
113 + 71411 = 71524
137 + 71387 = 71524
191 + 71333 = 71524
197 + 71327 = 71524
263 + 71261 = 71524

Showing the first eight; more decompositions exist.
