Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71590, here are decompositions:

41 + 71549 = 71590
53 + 71537 = 71590
107 + 71483 = 71590
137 + 71453 = 71590
179 + 71411 = 71590
191 + 71399 = 71590
227 + 71363 = 71590
251 + 71339 = 71590

Showing the first eight; more decompositions exist.
