Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127566, here are decompositions:

17 + 127549 = 127566
37 + 127529 = 127566
59 + 127507 = 127566
73 + 127493 = 127566
79 + 127487 = 127566
113 + 127453 = 127566
163 + 127403 = 127566
167 + 127399 = 127566

Showing the first eight; more decompositions exist.
