Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71558, here are decompositions:

7 + 71551 = 71558
31 + 71527 = 71558
79 + 71479 = 71558
139 + 71419 = 71558
199 + 71359 = 71558
211 + 71347 = 71558
229 + 71329 = 71558
241 + 71317 = 71558

Showing the first eight; more decompositions exist.
