Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127500, here are decompositions:

7 + 127493 = 127500
13 + 127487 = 127500
19 + 127481 = 127500
47 + 127453 = 127500
53 + 127447 = 127500
97 + 127403 = 127500
101 + 127399 = 127500
127 + 127373 = 127500

Showing the first eight; more decompositions exist.
