Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127452, here are decompositions:

5 + 127447 = 127452
29 + 127423 = 127452
53 + 127399 = 127452
79 + 127373 = 127452
89 + 127363 = 127452
109 + 127343 = 127452
131 + 127321 = 127452
151 + 127301 = 127452

Showing the first eight; more decompositions exist.
