Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127506, here are decompositions:

13 + 127493 = 127506
19 + 127487 = 127506
53 + 127453 = 127506
59 + 127447 = 127506
83 + 127423 = 127506
103 + 127403 = 127506
107 + 127399 = 127506
163 + 127343 = 127506

Showing the first eight; more decompositions exist.
