Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127554, here are decompositions:

5 + 127549 = 127554
13 + 127541 = 127554
47 + 127507 = 127554
61 + 127493 = 127554
67 + 127487 = 127554
73 + 127481 = 127554
101 + 127453 = 127554
107 + 127447 = 127554

Showing the first eight; more decompositions exist.
