Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71548, here are decompositions:

11 + 71537 = 71548
137 + 71411 = 71548
149 + 71399 = 71548
311 + 71237 = 71548
401 + 71147 = 71548
419 + 71129 = 71548
467 + 71081 = 71548
479 + 71069 = 71548

Showing the first eight; more decompositions exist.
