Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127524, here are decompositions:

17 + 127507 = 127524
31 + 127493 = 127524
37 + 127487 = 127524
43 + 127481 = 127524
71 + 127453 = 127524
101 + 127423 = 127524
151 + 127373 = 127524
181 + 127343 = 127524

Showing the first eight; more decompositions exist.
